Can we use comma before infinitive "to" in general. I ruled out A because of this and selected B.
Heyrahul16singh28 ,
It depends on the structure of the sentence. If you are using the information before the "To" infinitive as a modifier such that we do have another comma before the start of the modifier, then it is perfectly fine to use a comma.
For example:
I am drinking water, to get hydrated.
Here, the usage is wrong. You cannot have a comma before "To"
