The 0.855 is the value of the cd of the external mouthpiece.

@Sravan.
Mouthpiece is something with which you talk to in case of a phone. It is located at the bottom of the phone. If the mouthpiece is long then the person you're talking to will hear you better which means better discharge of sound. Hence discharge is directly proportional to Length.

What about internal mouthpiece?

That is discharge formula not of coefficient of discharge.

Answer D is correct, in already above written discharge formula, You all are considering as constant value i.e .855, but if we take the length of mouth piece in consideration then, Cd will decrease with increase in length as it increases friction resistance value in the wall of the mouth piece.

Yes Ans C is correct.
It depends on the area of the external mouthpiece.
Q = 0.855a√2gh.
It depends on the area of the external mouthpiece.
Q = 0.855a√2gh.

What is the correct one?

Q = 0.855a√2gh.
So it proportional to C.s.a of Mouthpiece.
So C is the correct answer!
So it proportional to C.s.a of Mouthpiece.
So C is the correct answer!

Its D is 100 right. If length of mouthpiece is long then discharge of fluid tend to decrease.
