Solution

The answer is the third one (or C): blastomeres.

Explanation for each option: a.) Gastrulas - Incorrect. Gastrulas are formed later in development during the process of gastrulation, not during cleavage. b.) Zygotes - Incorrect. A zygote is the initial cell formed when a sperm cell fertilizes an egg cell. Cleavage occurs after the zygote is formed. c.) Blastomeres - Correct. Blastomeres are the cells that result from the division of the zygote during the process of cleavage. d.) Oocytes - Incorrect. Oocytes are immature egg cells that undergo maturation before fertilization.

Summary: During the process of cleavage, the zygote divides to form new cells called blastomeres.
