Answer:

A

Explanation:

Normal distribution also called Gaussian distribution is a probability distribution of scores, stocks and others known collectively as data, where several of the data are close to the average score and few are either extremely high or low. This phenomenon is describe as the distribution is symmetrical about the mean with few  data at both far end from the mean.

Normal distribution has a bell curve shape with 68% of the data within ± 1 standard deviation from the mean, 95% of the data within ± 2 standard deviation of the mean and 99.7% within ± 3 standard deviation of the mean.
