The size and appearance of these particles are highly suggestive of parapoxvirus virions(using Distributive Law) => p^2 pq qp q^2 => p^2 q^2 (pq is same as qp so both nullify each other) So, the correct answer is (pq)x(pq) = p^2 q^2P = 79, q = 113, e = 2621 n = pq ø(n) = (p1)(q1) n = 79 x 113 = 27 ø(n) = 78 x 112 = 8736 e = 2621 d = ??? 2 È'P q _"X "¯^
