Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern. ID-LG-OQLG-OJ-RT
MI-QL-TU
MI-QK-TV
NI-QL-TV
NI-QK-TU
NI-QL-TV
Observe the constant jump pattern between letters: 1st triad (ID-LG-OQ) shows first letters I(+3)=L(+3)=O and second letters D(+3)=G(+3)=J. Apply this +3 shift to the starting letters of the target.

Analyze the existing pattern
Triad 1: ID-LG-OQ. First letters: I(9) тЖТ L(12) тЖТ O(15). Rule: +3. Second letters: D(4) тЖТ G(7) тЖТ J(10). Wait, let's look at the given structure. The pattern is (First letter of word 1, First letter of word 2, First letter of word 3) and (Second letter of word 1, Second letter of word 2, Second letter of word 3).
Mapping the letter movement
Looking at ID-LG-OQ: I to L is +3, L to O is +3. D to G is +3, G to J is +3. Triad 2: LG-OJ-RT: L to O is +3, O to R is +3. G to J is +3, J to M(Wait, the example says RT). Checking the second element of RT: If the logic is +3 on both letters, MI тЖТ M+4=Q, I+3=L тЖТ QL. Q+3=T, L+3=O (Wait, the option is TV). Let's re-verify: M(13) +4 = Q(17), I(9) +3 = L(12). Q(17) +3 = T(20), L(9) + 10... No, simply: M+4=Q, I+3=L. Q+3=T, L+10=V. Correct pattern is +4, +3 for first letters and +3, +10 for second letters.
A: MI-QL-TU does not follow the correct V increment. B: MI-QK-TV fails the L to K transition. D: NI-QK-TU starts with the wrong letter compared to the prompt requirements.
B is correct because the series follows a specific incremental shift in both character positions across the three pairs.
In letter-series analogies, always calculate the numerical difference between corresponding letters of the first and second triplets to quickly spot the constant offset.
