Select the letter-cluster that can replace the question mark (?) in the followingseries.
qDx, nHs, kLn, hPi, ?
The series follows pattern as,
(q - 3)(D + 4)(x - 5) = nHs
(n - 3)(H +Â 4)(s - 5) =Â kLn
(k - 3)(L + 4)(n - 5) =Â hPi
(h - 3)(p + 4)(i - 5) = eTd
$$\therefore$$ The correct answer is option C.
