1 votes 1 votes The correct option is B i.e. 2/n Because when we expand out the expression everything except 'n' in the denominator will be canceled out with everything except '2' of the numerator giving the answer as 2/n sushil1997 answered Sep 28, 2018 sushil1997 comment Share Follow See all 0 reply Please log in or register to add a comment.
