Answer:
The correct answer is option C.Tetrad.
Step-by-step explanation:
We denominate tetrad to the set of 4 spores. These spores are grouped into two sets of identic chromatids.
The tetrad is formed during meiosis by two homologous chromosomes, that is, one from the mother and one from the father.
Meiosis is a process of cell reproduction, where a diploid cell divides generating four haploid cells.
Diploid cells are those that have two series of chromosomes, while haploid cells are those that have only one series of chromosomes.
Given this information we can verify that the correct answer is tetrad.
