Concept:
ASCII code represents characters using numerical values. In hexadecimal notation, each English capital letter has a fixed ASCII value.
Step 1: Write ASCII hexadecimal value of each character.
\[
G = 47
\]
\[
I = 49
\]
\[
R = 52
\]
\[
L = 4C
\]
Step 2: Arrange according to the word “GIRL”.
The word is:
\[
G\ I\ R\ L
\]
So, the hexadecimal ASCII code is:
\[
47\ 49\ 52\ 4C
\]
\[
\therefore \text{Correct Answer is (C)}
\]
