Answer:

1. D. reproduce sexually

2. B. Cambrian

3. A. bilateral symmetry

Explanation:

  • The formation of an embryo (zygote) is a characteristic of sexual reproduction since it occurs as a result of the union of a female gamete with a male gamete.
  • The Cambrian is the period in which most groups of animals appear in the fossil record. The animals that characterize the Cambrian fauna are basically groups of invertebrates such as annelids, arthropods, porifers and echinoderms.
  • Of the described options, the only characteristic of mollusks is bilateral symmetry, since they are not segmented and are soft-bodied animals, ie, they don't have internal skeletons or shells.
