7- The Operating Characteristic (OC) curve for a good sampling plan is the one whose behavior of the probability of acceptance, P(A), with respect to the proportion (p) of defective items is such that: Select one: a. P(A) is consistently high for all values p b. P(A) is consistently lower for all values of p c. Higher values of P(A) for p values close to zero and smaller values of P(A) for higher values of p. d. Lower values of P(A) for p values close to zero and higher values of P(A) for higher values of p
