A battery consists of a variable number ' \( n \) ' of identical cells (having internal resistance ' \( r \) ' each) which are connected in series. The terminals of the battery are short circuited and the current I is measured. Which one of the graphs below shows the relationship between I and \( \mathrm{n} \) ?
(A)
(B)
