Explanation

DARE (option ‘B’). Use of the phrase SO EARLY in the sentence is making it clear that this sentence is not a request………..so ‘A’ & ‘ D’ both are impossible. This is not an order also…………so ‘C’ too is impossible. DARE (option ‘B)’ is correct………..means CAN YOU BE BRAVE ENOUGH TO WAKE ME UP SO EARLY ON A SUNDAY
