Answer: B. 95.0

Step-by-step explanation:

In statistics , the famous empirical rule says that " if the data is normally distributed then 68% of the observations will be contained within $\pm1$ standard deviations from the arithmetic mean, 95% of the observations will be contained within $\pm2$ standard deviations from the arithmetic mean and 99.7% of the observations will be contained within $\pm3$ standard deviations from the arithmetic mean".

Hence, B is the correct answer.
