Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

C. ...A -orthologs B- Paralogs Orthologs are homologous genes in different species that diverged from a single ancestral gene after a speciation event and paralogs are homologous genes that originate from the intragenomic duplication of an ancestral gene.
In the diagram A is pointing towards two shaded black squares and B is pointing towards one shaded black square and one unshaded white square. does this signify anything?
yes it means there is nothing much changed in A ...that's why orthologs whereas if one is having completely different colours means they are having major differences may be different lengths like alpha and beta hemoglobin so paralogs
