Correct Answer

✅ Option d — EJKNFTGP

Let's identify the shift pattern in the coding of

\displaystyle TEACHER \rightarrow VGCEJGT

by examining the alphabetical positions:
-

\displaystyle \text{T (20)} \xrightarrow{+2} \text{V (22)}

\displaystyle \text{E (5)} \xrightarrow{+2} \text{G (7)}

\displaystyle \text{A (1)} \xrightarrow{+2} \text{C (3)}

\displaystyle \text{C (3)} \xrightarrow{+2} \text{E (5)}

\displaystyle \text{H (8)} \xrightarrow{+2} \text{J (10)}

\displaystyle \text{E (5)} \xrightarrow{+2} \text{G (7)}

\displaystyle \text{R (18)} \xrightarrow{+2} \text{T (20)}

The pattern is a constant forward shift of

\displaystyle +2

for each letter.

Now, let's apply the

\displaystyle +2

shift to the word

\displaystyle CHILDREN

:
1.

\displaystyle \text{C (3)} \xrightarrow{+2} \text{E (5)}

\displaystyle \text{H (8)} \xrightarrow{+2} \text{J (10)}

\displaystyle \text{I (9)} \xrightarrow{+2} \text{K (11)}

\displaystyle \text{L (12)} \xrightarrow{+2} \text{N (14)}

\displaystyle \text{D (4)} \xrightarrow{+2} \text{F (6)}

\displaystyle \text{R (18)} \xrightarrow{+2} \text{T (20)}

\displaystyle \text{E (5)} \xrightarrow{+2} \text{G (7)}

\displaystyle \text{N (14)} \xrightarrow{+2} \text{P (16)}

Combining these letters, we get the code

\displaystyle EJKNFTGP

.

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