Caves form most commonly in
A
Granite
B
Sandstone
C
Limestone
D
Gneiss
Explanation: 

Detailed explanation-1: -Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Detailed explanation-2: -Limestone caves, which are formed primarily by rainwater and snowmelt, are by far the most numerous of all cave types. Limestone formations were created millions of years ago, often in shallow seas, largely from the accumulated remains of marine animals such as corals.

Detailed explanation-3: -A solutional cave, solution cave, or karst cave is a cave usually formed in the soluble rock limestone.

Detailed explanation-4: -Formation Process But most caves form in karst, a type of landscape made of limestone, dolomite, and gypsum rocks that slowly dissolve in the presence of water with a slightly acidic tinge.

Detailed explanation-5: -Limestone caves are the most common type of cave on our planet. The limestone that dissolves is carried away by groundwater to other areas where it is deposited in caves as stalactites, stalagmites, flowstone and other speleothems.
