Mark the wrong statement with respect to laminar flow condensation on a vertical plate

• A. The rate of condensation heat transfer is maximum at the upper edge of the plate and progressively decreases as the lower edge is approached
• B. The average heat transfer coefficient is two third of the local heat transfer coefficient at the lower edge of the plate
• C. At a definite point on the heat transfer, the film coefficient is directly proportional to thermal conductivity and inversely proportional to thickness of film at the point
• D. The film thickness increases as the fourth root of the distance down the upper edge
