Answer

Correct option: A.

Both assertion and reason are true and reason is the correct explanation of assertion.

In recombinant $\text{DNA}$ technology, widely used host for replication and amplification of recombinant $\text{DNA}$ are prokaryotic $E$. coli and the eukaryotic yeast.
They replicate very fast to form a large population which expressed desired gene.
Yeast artificial chromosome $\text{(YAC)}$ are important cloning tools for the analysis of complex genome such as that of humans.
They allow the maintenance, propagation and analysis of such genome in an experimentally tractable system, the yeast.
