Metamorphic rocks can form from the transformation of pre-existing rocks under high temperatures and pressures. Common parent rocks include shale, limestone, and granite. The minerals present in the parent rocks determine the types of metamorphic rocks that can form.
Igneous, sedimentary and pre-existing metamorphic rocks.
To form a metamorphic rock, two key factors are needed: heat and pressure. These conditions alter the mineral composition and structure of pre-existing rocks (igneous, sedimentary, or even other metamorphic rocks) without melting them. Additionally, the presence of chemically active fluids can facilitate mineral changes during the metamorphic process.
No.
Metamorphic rocks are made from the action of heat, stress, and pressure on pre-existing rocks, of either an igneous, or a sedimentary origin. Also, sometimes a metamorphic rock can be resculpted to form another metamorphic rock.

A pre-existing, igneous, sedimentary and metamorphic rock.
Sedimentary rocks such as shale, limestone, and sandstone can recrystallize to form metamorphic rocks like slate, marble, and quartzite, respectively. Igneous rocks like basalt and granite can also undergo recrystallization to form metamorphic rocks such as greenstone and gneiss.
a metamorphic rock is one which is formed from transforming pre existing rocks

No.
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.

Bloodstone is not a rock, but a gemstone variety of the mineral quartz, in cryptocrystalline form.
If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.
