(c) Rounded tip

(d) Straight tip

This question was posed to me by my school principal while I was bunking the class.

I would like to ask this question from Configuration Layout topic in section Configuration Layout and Loft of Aircraft Design

Answer 1

Right answer is (a) T.e. kick

The best I can explain: Above figure is often termed as trailing edge kick. A straightened out trailing edge will increase the flap chord. It also reduces induced drag. Rounded tip will permit air to flow around tip easily.
