Given series is in GP by observing we get , First term = 1 Common Ratio= 1/3 see picture!! The ans does not match with Given options because may be it printed wrong. Sum of nth terms can not be independent of n . Try to find sum of infinite terms of series we get 3/2 which excatcly matches with option (b). Hope you understand!!!
