Correct Answer: Active

Solution : The most appropriate choice is the third option.

Indolent refers to a tendency or disposition towards laziness or a lack of willingness to exert oneself, often resulting in avoiding activities or tasks that require effort or work.

The opposite of this would be active , which means engaging in action, being energetic, and not being lazy.

The meanings of the other options are as follows:

• Lazy describes someone who is unwilling or disinclined to work, exert effort, or engage in activities that require physical or mental exertion.
• Unskilled refers to someone who lacks proficiency, expertise, or training in a particular skill or set of skills.
• Sluggish refers to a lack of energy, slow movement, or a tendency to be inactive or slow in physical or mental responses.
