Question

A geologist finds rocks with dinosaur fossils.

What is most likely the approximate age of the rocks?

A.
1 thousand years old

B.
500 million years old

C.
70 million years old

D.
5 billion years old

Answer 1

It's being estimated that dinosaurs lived on Earth from about 237 million years ago to about 66 million years ago. So answers B and D are definately too "old", while answer A is too "young". I'd pick answer C as it's most probable.
