Correct Answer: Lethargic

Solution : The second option is correct.

• Spry describes someone who is lively, active, and agile, often in a nimble and energetic manner.
• Lethargic means being sluggish, tired, or lacking in energy.

The other options, agile, sleuth, and workaholic, do not serve as antonyms for spry. Agile is a synonym; sleuth refers to a detective; and workaholic pertains to someone addicted to work, which is not necessarily the opposite of being spry.

The meanings of the other options are:

• Agile: It can refer to physical agility in terms of movement or, more broadly, to mental agility, indicating the ability to think quickly and adapt to changing situations with ease.
• Sleuth: It is often used to describe someone who is adept at gathering and analysing information to uncover the truth.
• Workaholic: It is often used to describe individuals who have a compulsive need to work long hours and are preoccupied with their work to the extent that it negatively impacts other aspects of their lives, such as personal relationships, health, and leisure time.

Therefore, the correct answer is lethargic.
