Fossils would be most likely to be found in a rhyolite schist limestone peridotite quartzite

Fossils would be most likely to be found in a limestone.

Explanation:

Fossils are the remaining parts, impressions or any kind of evidence of the activities of any kind of organisms found within the rock record. Igneous and metamorphic rocks are subjected to very high temperatures, so they do not contain fossils. Sedimentary rocks are the only rocks that contain fossils.

limestone is a type of sedimentary rock of composition mainly of calcium carbonate in the form of  mineral calcite. It is most commonly formed in clear, warm, shallow marine waters .

Fossil formation can take over millions of years .

Hence, the correct statement formed is -

Fossils would be most likely to be found in a limestone.
