Oolitic limestones form in a shallow marine environment. Oolitic limestones are composed of small, rounded, and often concentrically layered grains known as ooids.
The option (A) is correct.
These ooids form in shallow, warm, and clear marine waters, typically in tropical or subtropical regions. They precipitate from calcium carbonate that has been chemically dissolved in the water. Fossiliferous limestones, on the other hand, may form in various marine and non-marine environments and contain the preserved remains of ancient organisms.
Crystalline limestones can also form in different settings and are characterized by the presence of mineral crystals. However, oolitic limestones specifically indicate a shallow marine origin.
