if->return vs. if->else efficiency

Question

This may sound like a silly question, and I hesitated to post it, but still: if something needs to run only in a certain condition, which of these is more efficient:

Answer 1

Performance is more or less the same in both the cases. Therefore it becomes more of a style or preference question.

I personally prefer writing if--> return i.e. case B because it makes the code to look cleaner and easy to read specially if the code comprises of complex nested conditions.
