Unicellular organisms would most likely have

isogametes
anisogametes
oogametes

Option A, Isogametes

Explanation:

Unicellular organism mostly reproduce asexually and hence the offspring formed are exactly same to the parent cell in all respects. An isogametes produces gametes which have same size and structure as that of parents cell.  While an anisogametes  differ in size and structure as the male gamete is smaller and motile as compared to the female gamete.

An oogametes is specifically a large female gamete.

Hence, option A is correct

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
