In order for the sample proportion to be assumed to be normally distributed, the sample size has to be large enough, specifically having at least 10 successes and 10 failures. Choice A and B satisfy only one of the criteria, which is not sufficient. The population being known is not relevant to whether the sample proportion is normally distributed.
