Regarding the Acceptance-Rejection RV generation method, select the incorrect statement: O (a) A-R attempts to gain efficiency by generating an easy "surrogate" random variable that is somewhat similar to the actual more-complicated random variable of interest. O (b) A-R can often be used even when a continuous RV doesn't have a closed-form inverse. O (c) The Box-Muller method is an A-R method. O (d) The number of sampling cycles required by A-R is a geometric RV. (e) The closer an A-R method's majorizing function is to the p.d.f. of interest, the better
