Correct Answer: sufficient

Solution : The first option is the correct choice.

The word adequate refers to being satisfactory or having enough of something to meet a particular requirement. On the other hand, the term sufficient also denotes having enough of something to meet a need or requirement.

The meanings of other options are as follows:

• Unfit means something that is not suitable or appropriate for a particular purpose
• Inept means lacking skill or ability, often inappropriately applied
• Meagre means lacking in quantity or quality, insufficient, or inadequate.

Therefore, the correct answer is sufficient.
