Coal is the only option being a solely organic product.
Sandstone, Limestone and Shales may contain considerable amounts of coalified organic matter of marine or continental origin (up to several per cent) but the larger fraction of material is detrital slicates in the case of sandstones and shales and carbonates in the case of a limestone.
Basalt does not belong because it is an igneous rock formed from volcanic activity, while shale, sandstone, and limestone are sedimentary rocks formed from different processes such as compression of sediment or accumulation of organic materials.
Coal and coral reef limestone are organic sediments salt is an evaporite Sandstone and conglomerate are sedimentary deposit rocks the latter from a high energy environment. They are ALL sedimentary deposits.

Limestone is a chemical sedimentary rock formed from the precipitation of calcium carbonate. It is primarily composed of mineral calcite, which is organic in origin but can also form through inorganic processes. So, limestone is considered both a chemical and organic sedimentary rock.
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
Sandstone is not an organic sedimentary rock, but limestone is.
There is no such ting as "lystone" Sandstone is a sedimentary rock. Limestone is a sedimentary rock of organic origin.
Sedimentary, mainly versions of sandstone and limestone, both chemical and/or organic.
Clastic sedimentary rocks, like conglomerate and sandstone.
Basalt does not belong because it is an igneous rock formed from volcanic activity, while shale, sandstone, and limestone are sedimentary rocks formed from different processes such as compression of sediment or accumulation of organic materials.
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
Coal and coral reef limestone are organic sediments salt is an evaporite Sandstone and conglomerate are sedimentary deposit rocks the latter from a high energy environment. They are ALL sedimentary deposits.
Sedimentary rocks are rocks made up of rock fragments(sediment)and cemented and compacted together over time. There are three sub groups to sedimentary rock organic,clastic,and chemical.Some rocks under sedimentary rocks are limestone,sandstone,and shale.

Sandstone, limestone, shale, and conglomerate are examples of sedimentary rocks. Sandstone is formed from compacted sand grains, limestone is made from organic remains like shells or coral, shale is composed of fine clay particles, and conglomerate consists of rounded pebbles cemented together.
Limestone is a chemical sedimentary rock formed from the precipitation of calcium carbonate. It is primarily composed of mineral calcite, which is organic in origin but can also form through inorganic processes. So, limestone is considered both a chemical and organic sedimentary rock.
Sedimentary rocks, such as sandstone and limestone, are commonly associated with oil deposits. When organic matter accumulates and gets buried over time, it can transform into oil and become trapped in porous rock formations. These sedimentary rocks serve as reservoirs for oil extraction.
