Answer 2

Answer:

A) He could study how the snails develop.

Explanation:

Fetal science or embryology is used as an evidence of evolution. Comparative study of embryos in vertebrates/chordates shows that there is lot of similarity in them at the initial stages whereas this similarity decreases gradually. This similarity in the development of embryos represents common origin of organisms.
