Which statement is most likely correct?

Rock B may have fossils.
Rock A may have shiny, glassy surface.

The correct answer is the first choice “Rock B may have fossils”
Because rock B is the rock that cools off on top of Rock A, there may be animals or other living organisms that may have died during the eruption and that causes rock B to form over it.
