D sedimentary rocks
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Fossils are almost exclusively found in sedimentary rocks (like sandstone, limestone, shale). These rocks form from layers of sediment that can gently bury and preserve remains. Igneous rocks (from magma) and metamorphic rocks (altered by heat/pressure) would destroy organic remains.

Hint

These rocks form from layers of mud, sand, or silt, which can gently cover and preserve organisms.
