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.
DRAGON reversed is NOGARD. Then shift each by +1: N→O, O→P, G→H, A→B, R→S, D→E gives OPHBSE. Check: N→O, O→P, G→H, A→B, R→S, D→E. Close to option A structure.
D→H(+4), E→E, F→F, R→R, O→O, S→T(+1), T→Z(+6). Pattern unclear - verify against options.
C(consonant)→C(+0? or rule differs), R(consonant)→U(+3), I(vowel)→I(no shift), C→D(+1), K→M(+2), E(vowel)→G(+2 not +3), T→U(+1). Pattern shows vowels handled differently.
DIGITAL: Swap first and last: LITIGAD. Now shift each by 3: L(+3)=O, I(+3)=L (no, L=12), T(+3)=W, I(+3)=L (no), G(+3)=J, A(+3)=D, D(+3)=G. That gives OLWLJDG. Re-checking swaps: D and L swap in DIGITAL→LITIGAD. I(+3)=L, T(+3)=W, wait I(9)+3=L(12), yes. Then shifting: L→O(+3, L=12→O=15), I→L(+3, I=9→L=12), T→W(+3), I→L, G→J(+3), A→D(+3), D→G(+3). So OLWLJDG. But wait, the swapped word is LITIGAD not LITIGA + D separately. Starting over: DIGITAL reversed (swap ends) = LATIGID. Now each +3: L→O, A→D (no, A=1→D=4, yes), T→W, I→L, G→J, I→L, D→G. = ODWLJLG. Still not matching. Checking option B OJOOXKA differently suggests another pattern.
Vowels (A,E,I,O,U) → next consonants (B,F,J,P,V). Consonants → next vowels in cycle. P(consonant)→next vowel(A), Y(consonant)→O(next in pattern), T(consonant)→U, H(consonant)→I, O(vowel)→P (no, should be next consonant: A goes to B. Here O→next consonant after O=P? No. Vowels→next consonant: A→B, E→F, I→J, O→P, U→V. So O→P. But option shows O not P. Re-reading: consonant→next vowel. P→first vowel after P=U? Or in order: A,E,I,O,U cycling. Next after U is A). Y→E (Y is consonant, next vowel: A,E,I,O,U → cycle), T→I, H→A, O→P (vowel to consonant: O→next consonant: P,Q,R... → P). AOUIOA or AOUIPA. Closest is AOUIAA.
FRIEND→GSKFNC: F(+1)=G, R(+1)=S, I(+1)=J (no, K=11), E(+1)=F, N(+1)=O (no, N=14), D(+1)=C (no, E=5). Different pattern: reverse then modify. FRIEND reversed = DNEIVF. D→G(+3), N→S(+5), E→K(+6), I→F(-3), R→N(-4), F→C(-3). For DANGER reversed = REGNAD. R→E(-13 or +13), E→B(-3), G→O(+8), N→H(-6), A→Q(+16), D→S(+15) = EBOHQS (approximately with wrapping logic)
PLANET→TSYXPD: Reverse the word first. PLANET reversed = TENALP. T→T(0), E→S(-6 or wraps), N→Y(+11), A→X(+23 or -3), L→P(+4), P→D(-12). For MOBILE reversed = ELIBOM. E→Q(+12), L→Z(+14), I→O(+6), B→X(+22), O→J(-5), M→C(-10) = QZOXJC (approximately, with wrapping)
