S→T, Q→R, U→21 (no, 21st letter is U, so 21 or position 21? Using A=1 rule: U=21... but shown as single. Let me use: U=21 shown as 21. A=1. So S(+1)→T, Q(+1)→R, U(21 from A=1,E=5,I=9,O=15,U=21)→21? Answer shows 15 for code, so E=5, U should differ. With A=1,E=5,I=9,O=15,U=21: 15 is O. For SQUARE: S→T, Q→R, U→21, A→1, R→S, E→5? Try TGRVF5: T(S→T), G(Q→R?? Q+1=R not G). Let me trust answer C: TGRV15 means A=1, E=5... final vowel code is 1+5=6? Or 15 from O. Answer format may show 15 for both vowels combined or last vowel.
Pattern: Consonants→position in alphabet. R=18 (no, 1 suggests R=1? Or vowels stay, consonants to number). If I and E are vowels staying: R→18 or code 1? Checking: R(2nd consonant)=1, D(4th consonant)=4, G(7th consonant)=7. Checking FRIEND: F(1st)=6, R=1, I=9?, E=5, N=14, D=4. Answer B fits.
Q→O, U→S (wait: U-2=S not O), A→Y, L→J, I→G, T→R, Y→W. Correction: Q(-2)=O, U(-2)=S, A(-2)=Y, L(-2)=J, I(-2)=G, T(-2)=R, Y(-2)=W = OSYJGRW. Closest option A logic holds differently.
M=12th consonant, A=A, R=18th consonant, K=11th consonant, E=E, T=20th consonant. Code: 12A18E8 (T=20 is wrong, should be coded). M=12, R=18, K=11, T=20. Answer shows 12A18E8, so T must be 8 in some system, or answer key differs.
P is 16th letter of alphabet, at position 4 in ELEPHANT: 16×4 = 64 (verify: question asks contribution, P=16, position 4: 16×4=64, but option C=84 suggests different calculation).
Positions: T=20, R=18, I=9, A=1, N=14, G=7, L=12, E=5. Sum = 20+18+9+1+14+7+12+5 = 86 (verify: may be different rule).
MONEY reversed: YENOM. Each shifts back -1: Y→X, E→D, N→M, O→N, M→L = XDMNL (re-verify: Y→X(no, shift back), E→D, N→M, C→L gives LDMCW).
SCIENCE: S-C-I-E-N-C-E has 4 vowels (doubled = 8) and 3 consonants (halved = 1.5 ≈ 2) = 8+2 = 10 letters (verification needed, closest is B=11).
1st & last letters remain same, middle letters: A→Z, P→U, T→U for LAPTOP. For TABLET: T stays, A→Z, B→V, L→W, E→U, T→U = TZVWWU (checking: option shows A as TZVMWU - requires verification of exact rule).
P→D, L→Q, A→Z, T→U, F→Q, O→W, R→J, M→N shows varying shifts: P(+/−), L(+5), A(+25), etc., indicating polyalphabetic (varying) substitution rather than fixed Caesar shift.
