Mita . . . . . . . . opening show room tomorrow. A. why B. will be C. what D. will

The correct answer is: will be.

The verb “will be” is used to express future events. In this case, the sentence is about Mita opening a showroom tomorrow. Therefore, the correct answer is “will be”.

The other options are incorrect because they do not express future events. The verb “why” is used to ask for reasons. The verb “what” is used to ask for information about something. The verb “will” is used to express willingness or intention.

Here are some examples of how the other options could be used in a sentence:

• Why is Mita opening a showroom tomorrow?
• What is Mita going to do in her showroom?
• Mita will be opening a showroom tomorrow.
