When resistors are connected in parallel, the equivalent resistance is calculated by taking the reciprocal of the sum of the reciprocals of each resistor. In this case, since all the resistors are identical, we can represent the equivalent resistance as R_eq = R/x, where x is the number of resistors connected in parallel. Therefore, x = N, so R_eq = R/N.  So, the correct option is (A).
