Question

they all use \o\ composition.
they all use \u\ composition and frame - within - a - frame.
they all use rule of 3rds.
they all use \u\ composition.

Explanation:

To determine the correct option, analyze the visual compositions:

1. The left image has a rock arch (frame - within - a - frame) and a U - shaped formation from the rocks/shoreline.
2. The right image: The floral arrangement and the figure create a U - like flow, and the scene might have a frame - within - a - frame (e.g., the space around the figure and flowers).
3. Option 1 ("O" composition) is incorrect as there's no circular focus. Option 3 (Rule of 3rds) isn't evident. Option 4 ("U" composition only) misses the frame - within - a - frame element seen in the left (rock arch as a frame) and implied in the right. Option 2 matches both "U" composition (curved/flowing U - like elements) and frame - within - a - frame (rock arch in left, contextual framing in right).

Answer:

B. They all use "U" composition and frame - within - a - frame.
