Select the triad which follows the same pattern as that followed by the two triads given below, Both triads follow the same pattern.

PK - RM - TU

HC - JE - LM

In both triads (PK - RM - TU and HC - JE - LM), the first letters increase by +2,+2.

Example: P→R(+2)→T(+2) and H→J(+2)→L(+2).

The second letters increase by +2,+8

Example: K→M(+2)→U(+8) and C→E(+2)→M(+8)

First letters (M → O → Q):
+2,+2→ Matches the pattern.

Second letters (H → J → R):
+2,+8 → Matches the pattern.

This is the only option that perfectly follows the +2,+2 and +2,+8 pattern.
