0A bob is attached to a string as shown in the figure below. At the lowest point, it is given a horizontal velocity \( u \). The bob rotates complete circle in vertical plane. For different values of \( u \), it can have different total acceleration at different points. For each of the points marked in column I, match the possible direction(s) of the total acceleration given by statements (i), (ii), (iii), (iv), and (v).
Match the situation of the particle with the statement given in Column II.
(1) \( \mathrm{A}-\Pi \mathrm{I} \)
(2) B-I, IV, V
(3) C-I, II
(4) D-III, IV
