The question about Mohan's first effort at a monitor is asking for a specific detail from a story, likely involving imaginative or fictional characters or situations. The multiple-choice options suggest playful and creative scenarios featuring animals in unusual costumes:
A dog in a school uniform
A monkey in a swimsuit
A platypus in a top hat
An elephant in a ball gown
The correct choice from these options is 'A monkey in a swimsuit.' This selection might align with the story's theme or humor, portraying whimsical situations.
If the story is not provided, consider the playful nature of the choices to understand the essence of Mohan's effort, which might relate to an artistic or humorous attempt.
