The correct answer is C. doesn’t drink.
The sentence is in the present simple tense, so we need to use the present simple form of the verb “drink”. The present simple form of “drink” is “drinks”. However, we need to use the negative form of the verb, because the sentence is about something that Jane does not do very often. The negative form of “drinks” is “doesn’t drink”.
The other options are incorrect because they are not the present simple form of the verb “drink”. Option A, “not drinks”, is the negative form of the present continuous tense. Option B, “have not drink”, is the past participle of the verb “drink”. Option D, “is not drinking”, is the present continuous form of the verb “drink”.
Here is a table that shows the different forms of the verb “drink”:
| Tense | Form |
|—|—|
| Present simple | drinks |
| Present continuous | is drinking |
| Past simple | drank |
| Past participle | drunk |
| Future simple | will drink |
| Future continuous | will be drinking |
| Perfect simple | has drunk |
| Perfect continuous | has been drinking |
I hope this helps!
