User comments below. All of them might not be correct.

Ans is B.
There are 6 t's in the given string., so the count will be 6. And every 't' or 'T' in the given string are replaced by '_'.

A and B both are same as well as correct at every appearance of 't' or 'T' in givenstring count is incremented and that character will get replaced by '_'.
