The correct answer is option B.

MHC or The major histocompatibility complex is a series of genes that have information and rise to cell surface proteins required for the adaptive immune system to recognize the pathogen or the foreign molecules, There are three classes of MHC - MHC1, MHC2, and MHC3.
MHC class II generally present only on antigen-presenting cells such as single nuclear phagocytes, dendritic cells, thymic and B cells.
Thus, the correct answer is option B.
Only the last one provides an actual evidence of having a common ancestor. The rest can be a result of living in a similar environments that makes life easier. For example, many species live next to water, as water provides more fertile ground for plants, and they might have similar behaviors (searching for water) but they might not be closely related.
so the correct answer is D.
