A Correct answer
Explanation

When limestone undergoes metamorphism, it recrystallizes to form marble. The heat and pressure cause the calcite crystals in limestone to grow larger and interlock, creating the characteristic crystalline texture of marble. Dhrain appears to be a typo, graben is a fault block, bajada is an alluvial slope, and bhabar is a piedmont plain.
