Which of the following terms follows the trend of the given list?
RSPQPQPQ, PSRQPQPQ, PQRSPQPQ, PQPSRQPQ, PQPQRSPQ, _______________.

Expression : RSPQPQPQ, PSRQPQPQ, PQRSPQPQ, PQPSRQPQ, PQPQRSPQ, _______________.

The above series is a combination of 4 'PQ', but in each alternative term starting from the left, 1 set of PQ is replaced by RS and in the even number of terms, 1 set of QP is replaced by SR shifting one place to the right.

Thus, in the missing term (6th term), 3rd Q is replaced by S and following P by R = PQPQPSRQ

=> Ans - (C)
