(A) During the process of meiosis,specifically in the pachytene stage of prophase-$I$,homologous chromosomes pair up to form a structure called a bivalent or tetrad.Each chromosome consists of two sister chromatids.Since a bivalent is composed of two homologous chromosomes,and each chromosome has two chromatids,the total number of chromatids in a bivalent is $2 + 2 = 4$.Therefore,a bivalent is also known as a tetrad because it contains four chromatids.

What is the number of chromatids in a bivalent of homologous chromosomes during synapsis?
