Friends according to me the answer should be e = 1, which is not any option and question says answer is 2/3 which is Option (a). Please try to help me in this.
I will appreciate the help.

The method you applied is applicable for two particle collision only. You'll need to do adjustments before applying this method.

Well if I'll conserve momentum for the whole system there would be two lines of imapact.
Ok first I'll do some adjustment in that and then will continue.
