Pick Out the Wrong Statement

Pick out the wrong statement.

A) The condensing film co-efficient is about 3 times lower for vertical condenser as compared to the equivalent horizontal condenser for identical situation
B) Film co-efficient for vaporisation decreases as a result of vapor binding
C) In industrial practice, sub-cooling of condensate is required, when the condensate is a volatile liquid and is to be transferred for storage
D) Overall heat transfer co-efficient in a heat exchanger is controlled by the value of the film coefficient, which is higher
