Correct Answer: Skinny

Solution : The third option is the correct answer.

"Slim" typically suggests a pleasing or attractive thinness, while "skinny" may sometimes imply a more extreme or gaunt appearance. However, in common usage, they are often used synonymously to describe someone or something with a lean physique.

The meanings of other options are as follows:

• Flashy means showy or ostentatious, usually in a flamboyant or extravagant manner.
• Rosy refers to having a pink or healthy complexion, or it can signify something optimistic or positive.
• Moody describes someone who experiences frequent changes in mood or temperament, often characterised by mood swings or unpredictability.

Therefore, the correct answer is skinny.
