Please help

Hi, Teachers my apology from beginning for such a long post with 26 questions at one go but I need your help to resolve this.

There are 26 questions with 100 marks and after giving the test in computer my score was 90.

I am guessing the 1st one is not correct.But apart from that rest all 25 answers seems correct to me as per different response from different teachers from this forum or from internet. 

I am not sure that even if the 1st one is wrong, then also it will carry 10 marks to bring it down from 100 to 90. There must be another 1 or 2 answers which are not correct and I am not able to find it out. 

Please and please help me in finding those hidden ones.

I have BOLD my answers for each.
