Pick out the correct statement pertaining to Venturimeter.
(A) A Venturimeter with a fixed pressure drop discharges more, when the
flow is vertically downward, than when the flow is vertically upward

(C) For a fixed pressure drop, the discharge of a gas through a Venturimeter
is greater, when compressibility is taken into account, than when it is neglected
(D) None of these
