Solution
The correct option is B Bacteriophage
Bacteriophage is a double-stranded DNA containing virus which infects bacteria. Helical contractile sheath is found around the tail of bacteriophage. The tail structure is attached to one end of the head axis. It has several protein components: an inner core or spike is surrounded by a helical contractile sheath to which is attached a hexagonal baseplate and six tail fibers. Hence, D is the correct option.
