Detailed Solution & Explanation

To find which word is coded as **VCTIGVU**, let us first analyze the relationship between the word **HONEY** and its code **JQPGA** by converting the letters to their alphabetical positions (where A=1,B=2,…,Z=26\displaystyle A = 1, B = 2, \dots, Z = 26):

- H (8)→J (10)  ⟹  Shift of +2\displaystyle H\ (8) \to J\ (10) \implies \text{Shift of } +2
- O (15)→Q (17)  ⟹  Shift of +2\displaystyle O\ (15) \to Q\ (17) \implies \text{Shift of } +2
- N (14)→P (16)  ⟹  Shift of +2\displaystyle N\ (14) \to P\ (16) \implies \text{Shift of } +2
- E (5)→G (7)  ⟹  Shift of +2\displaystyle E\ (5) \to G\ (7) \implies \text{Shift of } +2
- Y (25)→A (27)  ⟹  Shift of +2\displaystyle Y\ (25) \to A\ (27) \implies \text{Shift of } +2

We observe a constant shift of +2\displaystyle +2 forward. Therefore, to decode the code word **VCTIGVU** back to the original word, we must shift each letter backward by −2\displaystyle -2 positions:

- V (22)−2=20  ⟹  T\displaystyle V\ (22) - 2 = 20 \implies \mathbf{T}
- C (3)−2=1  ⟹  A\displaystyle C\ (3) - 2 = 1 \implies \mathbf{A}
- T (20)−2=18  ⟹  R\displaystyle T\ (20) - 2 = 18 \implies \mathbf{R}
- I (9)−2=7  ⟹  G\displaystyle I\ (9) - 2 = 7 \implies \mathbf{G}
- G (7)−2=5  ⟹  E\displaystyle G\ (7) - 2 = 5 \implies \mathbf{E}
- V (22)−2=20  ⟹  T\displaystyle V\ (22) - 2 = 20 \implies \mathbf{T}
- U (21)−2=19  ⟹  S\displaystyle U\ (21) - 2 = 19 \implies \mathbf{S}

Putting the decoded letters in sequence, the original word is **TARGETS**.

Hence, **Option C** is the correct answer.
