Solution

The correct option is D Two homologous chromosomes each with two chromatids
Tetrads are formed in prophase-I of meiosis I. A tetrad consists of two homologous chromosomes, each with two chromatids. Thus, it consists of 4 chromatids. The two chromatids that belong to the same chromosome are called sister chromatids and are joined at the centromere.
