(B) During the process of synapsis in Prophase-$I$ of Meiosis,homologous chromosomes pair up to form a bivalent or tetrad.Each chromosome consists of two sister chromatids.Since a bivalent consists of two homologous chromosomes,and each chromosome has two chromatids,the total number of chromatids in a bivalent is $2 + 2 = 4$.Therefore,each chromosome involved in synapsis contains $2$ chromatids.
