Explanation:

Let’s break it down, option by option:

- BDGT: B(2), D(4), G(7), T(20) – Gaps: +2, +3, +13 (the jump isn’t consistent)

- HJMP: H(8), J(10), M(13), P(16) – Gaps: +2, +3, +3 (a clear pattern starts: add 2, 3, 3)

- LNQJ: L(12), N(14), Q(17), J(10). Gaps: +2, +3, -7 (one backward, the rest forward—odd pattern)

- TVYB: T(20), V(22), Y(25), B(2). Gaps: +2, +3, +3 (but after Y instead of going forward, it wraps back to B—because after Z, alphabet goes to A, B etc.)

Here’s the thing:

HJMP and TVYB both use a "skip 2, skip 3, skip 3" letter pattern (and TVYB wraps back after Z).

LNQJ switches direction at the end, unlike the others.

BDGT has an irregular big jump, not the +3, +3.

So, the odd one out is BDGT because its pattern is totally different from the other three.

Correct answer:

Option: 2, BDGT
