c. Marble is a metamorphic rock that forms from a limestone protolith

Explanation:

Marble is a metamorphic rock with recrystallized carbon commonly in dolomite. maybe referred to as metamorphosed marble. Being characterised by veins of distinct colours, due to many impurities of clay, sills, sand, and iron-rich oxides. Before metamorphism, the calcite in the limestone is often in forms of fossil material and debris. As metamorphism progresses begins the crystals in rock grow larger and become easy to recognize. Marbles are commonly used as a building material in tiles and plates and interior decorative items as there resistance to abrasion and colour properties as they being uniform thickness and resistant to water.

Answermost of the time it would be ground into fine sediment,and sometimes they are carried away from the original location;

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.
