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.
There are organic rocks, like Limestone, and clastic (composed of fragments), like Sandstone. Within these groups there are others, like coal is organic and siltstone is clastic, but even within limestone and sandstone, there are further categories. There's oolitic limestone, chalk and 'shelly' limestones; and arkose, desert sandstone, orthoquartzite (generic sandstone), and others. Conglomerate is an interesting one, if you are after a rock that is not 'normal'.
Coal is the only rock on the list which is an organic / biogenic sedimentary rock. Sandstone and conglomerate are both clastic sedimentary rocks and basalt is a mafic extrusive igneous rock.

some examples of organic sedimentary rocks are coal and limestones
Sedimentary, mainly versions of sandstone and limestone, both chemical and/or organic.
Clastic sedimentary rocks, like conglomerate and sandstone.
Sandstone is a clastic, not organic, sedimentary rock.
Limestone is formed from particles derived from organic processes, usually in a marine environment. Sandstone particles are derived from the weathering and erosion of silicate bearing rocks, normally.
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.
Sandstone and shale Actually it is Organic, Clastic, and Chemical
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.
