Answer»

Correct option is (a) Poxvirus

Easy explanation: Poxvirus/ vaccinia virus does not get INCORPORATED into the genome of the host CELL. They reside in the cytoplasm and REPLICATE in the cytoplasm. Thus, they help in TRANSIENT transformation RATHER than permanent transformation. The genome size of pox/ vaccinia virus is 300 kb.
