  • DROESTNE

Detailed Solution & Explanation

To find how the word **PRESENT** is written in the given code:

Let us analyze the coding rule by studying how **MENTION** becomes **LNEITNO**:

1. **First Letter Rule:**
The first letter **M** is shifted backward by −1\displaystyle -1 position in the alphabet:
M−1=LM - 1 = L
2. **Remaining Letters Rule:**
The remaining letters of **MENTION** are **E, N, T, I, O, N**. We divide them into consecutive pairs and reverse each pair:
- Pair 1: (E,N)→NE\displaystyle (E, N) \to NE
- Pair 2: (T,I)→IT\displaystyle (T, I) \to IT
- Pair 3: (O,N)→NO\displaystyle (O, N) \to NO
Concatenating these reversed pairs gives **NEITNO**.

Combining both parts, we get **L** + **NEITNO** =LNEITNO\displaystyle = LNEITNO.

Now we apply this exact same rule to the word **PRESENT**:

1. **First Letter Rule:**
The first letter **P** is shifted backward by −1\displaystyle -1 position:
P−1=OP - 1 = \mathbf{O}
2. **Remaining Letters Rule:**
The remaining letters of **PRESENT** are **R, E, S, E, N, T**. We divide them into consecutive pairs and reverse each pair:
- Pair 1: (R,E)→ER\displaystyle (R, E) \to \mathbf{ER}
- Pair 2: (S,E)→ES\displaystyle (S, E) \to \mathbf{ES}
- Pair 3: (N,T)→TN\displaystyle (N, T) \to \mathbf{TN}
Concatenating these reversed pairs gives **ERESTN**.

Combining both parts, we get **O** + **ERESTN** =OERESTN\displaystyle = \mathbf{OERESTN}.

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