Step 1: Observe the word "ARCH" in Figure B. Four circular cutouts have been made within the letters. These cutouts contain unique sections of the letters.
Step 2: Compare the cutouts from Figure B with the given options (\( P, Q, R, S \)). The correct group should exactly match the missing sections in terms of alignment, shape, and letter strokes.
Step 3: After careful observation, the group labeled \( R \) contains the four exact cutouts extracted from "ARCH". The patterns within the circles align with the letter fragments in Figure B.
Thus, the correct answer is option C (\( R \)).
