Select the triad that follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern.
HO-JQ-LN
JQ-LS-NP​

HO-JQ-LN
JQ-LS-NP​

First letters: +2, Second letters: +2, then -3

HO → JQ → LN

H + 2 = J, J + 2 = L 

O + 2 = Q, Q - 3 = N 

JQ → LS → NP

J + 2 = L, L + 2 = N

Q + 2 = S, S - 3 = P

Checking options;

A) LS-NU-PR

L + 2 = N, N + 2 = P

S + 2 = U, U - 3 = R

(Follows the same logic)

Thus, correct option is (a).
