Find out the missing code for the figure (4) in the given series :

1. Analyze the pattern of letters in the boxes: Figure 1 contains T and U. Figure 2 contains T and V. Figure 3 contains W and V.
2. Notice the changes between consecutive steps: From box 1 to box 2, the bottom letter changes from U to V while the top remains T. From box 2 to box 3, the top letter changes from T to W while the bottom remains V.
3. Observe the structural elements of the central symbol in box 4: The symbol is identical to box 2, which corresponds to the combination of the letters U and V. Therefore, the missing code for box 4 is U over V.

Final Answer: Option C
