46 most fossils form in\na the sap of ancient trees\nb volcanic rock\nc sedimentary rock\nd rusty water

Answer

Answer:

C. sedimentary rock

Brief Explanation:

Fossils mainly form in sedimentary rock as it accumulates layers over time, preserving organic remains. Volcanic rock is formed from lava and is too hot for fossil - preservation. Sap of ancient trees can preserve some organisms but is not the most common place for fossil formation. Rusty water is not a typical medium for fossil formation.
