Answer: B. Wrap Text
The apt option would be Wrap text.
Step-by-step explanation:
This option allows the user to wrap the lengthy text in to number of lines so that it gets accommodated in the given size not extending length wise. Here only the breadth gets increased.
Merge & Center option will work only we want to club or combine two or more cells and center the text.
Conditional formatting works well when we want to do the format with a desired condition and does not suit for handling lengthier text.
Sort & Filter is to extract the necessary data based on some condition. So this does not suit the given objective.
