Respuesta :
It would be A, because a fossil forms after an animal dies, and hundreds to thousands of years of soil or sediment coversit's body, preserving it. :)
Answer:
The answer is A) a living thing dies and sediment is very slowly deposited on top of its body.
Explanation:
The formation of a fossil depends a lot on the chemical composition of the organism that has died. Generally, the hard materials of an organism such as bones tend to have a greater amount of minerals within their composition, which facilitates the formation of a fossil. In order for a fossil to form, it is necessary that all the soft tissues of the organism have disappeared and sedimentation of the organism occurs, which prevents decomposition. This fossilization process occurs in thousands of years.
