B Correct answer
Explanation

In WAY : SUW, the pattern is -2, -4, -6: W(23)-2=U(21), A(1)-4=W(23) wrapping from 27, Y(25)-6=U(21). For the first missing term, applying +2, +4, +6 to U(21) gives V(23), X(24), Z(26) = VXZ. For the second missing term after SUW, continuing the -2, -4, -6 pattern: S(19)-2=T(17) wrapping from 21, U(21)-4=V(22), W(23)-6=X(24) = TVX. This matches option B.

C Correct answer
Explanation

LUNCH : OWQEK shows the pattern: +3, +2, +1, +2, +3: L(12)+3=O(15), U(21)+2=W(23), N(14)+1=Q(17), C(3)+2=E(5), H(8)+3=K(11). Applying this to DINNER: D(4)+3=G(7), I(9)+2=K(11), N(14)+1=O(15), N(14)+2=P(16), E(5)+3=H(8), R(18)+?=? - wait, DINNER has 6 letters but the pattern only gives 5 results. The answer C is GKQPHT which has 6 letters. Let me recheck: LUNCH (5 letters) gives OWQEK (5 letters). DINNER (6 letters) should give 6 letters. D(4)+3=G(7), I(9)+2=K(11), N(14)+1=O(15), N(14)+2=P(16), E(5)+3=H(8), R(18)+?=? - pattern might cycle: +3, +2, +1, +2, +3, +2. R(18)+2=T(20) gives GKQPHT, which matches option C.
