Answer:
A) They share short homologies at their respective tips
Explanation:
The cells of human contain two types of chromosomes that is autosomal and sex chromosomes.
The 22 pairs of autosomal chromosomes in humans are formed by the pairing of these chromosomes during the meiotic phase via the formation of a structure called synaptonemal complex between homologous sequences.
However, the two types of sex chromosomes called X and Y are not similar in their length but they pair via the formation of synapse which involves very short homologous sequences called "pseudoautosomal regions". The formation of the synapse through this region is called the X-Y body.
