Solution

The correct option is B Binal
The arrangement of capsomere unit in the viral capsid determines the symmetry of the bacteriophage. Binal symmetry is a symmetry which is used for the bacteriophages having complex symmetry having icosahedral head and helical tail. Virus with a head having 12 vertices (corner), 20 facet (sides) and 30 edges is known as icosahedral. For example, T2 bacteriophage.
So, the correct answer is 'Bacteriophage T2'.
