Based on the passage, how does the boy feel about the pictures?

The boy's excitement about the pictures can be understood through his emotional response and enthusiasm when interacting with them. When a person feels excited, it often reflects a strong positive emotion, such as joy or eagerness, which may stem from looking at something visually stimulating or meaningful. This choice suggests that the boy's experience with the pictures is engaging and captivating for him, indicating that he finds pleasure or interest in what he sees.

The context in which excitement is conveyed can involve various aspects, including the vividness, the subject matter of the pictures, or the memories and thoughts they provoke in him. Therefore, his feelings toward the pictures reflect a dynamic and affirmative engagement rather than any sense of detachment, fear, or confusion that would be implied by the other options. These feelings would not accurately capture the essence of a positive reaction to visual stimuli, whereas excitement fits the scenario where the boy is actively and joyfully engaged with the images.
