Answer:
(a) sedimentary rocks
Step-by-step explanation:
Fossils are most commonly found in sedimentary rocks. This is because sedimentary rocks are formed from the remains of living things that have been buried in sediment. The sediment is then compacted and hardened over time, preserving the fossils.
Let's see the other options:
- Igneous rocks are formed from molten rock that cools and solidifies.
- Metamorphic rocks are formed when other rocks are subjected to heat and pressure.
- Neither of these processes is conducive to the preservation of fossils.
So, the best place to look for fossils is in sedimentary rocks.
