In a certain code, RAL is written as KCTN and SPEAK is written as CGRUM. How will AVOID be written in that code?

Options

A. FKQXC
B. KQXCF
C. XRXCT
D. KQVCB

Explanation

To solve the problem of how AVOID will be written in the given code, we can follow the steps outlined in the video transcript. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Code Pattern
From the examples given:
- RAL is coded as KCTN
- SPEAK is coded as CGRUM

We need to identify the pattern used to encode these words.

### Step 2: Analyze the First Example (RAL → KCTN)
1. Write down the letters of RAL: R, A, L
2. The last letter (L) is kept as it is.
3. Reverse the first two letters: A, R becomes R, A.
4. Move each letter two steps forward in the alphabet:
- R → T
- A → C
- L → N (last letter remains unchanged)

So, RAL becomes KCTN.

### Step 3: Analyze the Second Example (SPEAK → CGRUM)
1. Write down the letters of SPEAK: S, P, E, A, K
2. The last letter (K) is kept as it is.
3. Reverse the first four letters: A, E, P, S becomes S, P, E, A.
4. Move each letter two steps forward in the alphabet:
- S → C
- P → R
- E → G
- A → U
- K remains K

So, SPEAK becomes CGRUM.

### Step 4: Apply the Same Logic to AVOID
1. Write down the letters of AVOID: A, V, O, I, D
2. The last letter (D) is kept as it is.
3. Reverse the first four letters: A, V, O, I becomes I, O, V, A.
4. Move each letter two steps forward in the alphabet:
- I → K
- O → Q
- V → X
- A → C
- D remains D

So, AVOID will be coded as KQXC.

### Final Answer
Thus, AVOID is written as **KQXC** in the code.
