The question is asking for the correct form of the verb to complete the sentence. The given options are "increases", "increase", "is increase", and "are increase".

To find the correct answer, we need to consider the subject "The number of participants", which is a singular noun phrase. Singular subjects take singular verbs.
- Options A, B, and C all use singular verbs ("increases", "increase", "is increase"), but option D uses a plural verb ("are increase").
Thus, the correct answer is B. Increase.

Alternative method:
We can also identify the correct answer by looking at the structure of the sentence. The verb should agree with the subject in terms of number.
- The subject "The number of participants" is singular, so the verb should be in the singular form.
- Option B, "increase", is the only one in the singular form.

Therefore, the correct answer is B. Increase.
