Detailed Solution & Explanation

To find the code for the word **JAIPUR** based on the coding of **DELHI** as **EFMII**:

Let us first analyze the relationship and identify a typographical error in the question statement:
- If we look at the first four letters of **DELHI** and their code **EFMI**:
- D+1→E\displaystyle D + 1 \to E
- E+1→F\displaystyle E + 1 \to F
- L+1→M\displaystyle L + 1 \to M
- H+1→I\displaystyle H + 1 \to I
- The last letter **I** in **DELHI** is written as **I** in the code **EFMII**. This is a typographical error where the letter was copied without the +1\displaystyle +1 shift (which should have been I+1→J\displaystyle I + 1 \to J, giving the correct code EFMJJ\displaystyle EFMJJ).

This confirms the **+1\displaystyle +1 alphabetical shift rule** for each letter in the word. We apply this rule to the word **JAIPUR**:
- J+1→K\displaystyle J + 1 \to \mathbf{K}
- A+1→B\displaystyle A + 1 \to \mathbf{B}
- I+1→J\displaystyle I + 1 \to \mathbf{J}
- P+1→Q\displaystyle P + 1 \to \mathbf{Q}
- U+1→V\displaystyle U + 1 \to \mathbf{V}
- R+1→S\displaystyle R + 1 \to \mathbf{S}

Putting the letters in order, the code for **JAIPUR** is **KBJQVS**.

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