According to the Empirical rule,

If the population is normally distributed then, about 68% of the population lies within 1 standard deviation from the mean value.

Here, the data shows 68% percent of the area under the normal distribution.

This is equivalent to "plus or minus 1 standard deviation from the mean."

Hence, the correct option is : plus or minus 1 standard deviation from the mean.
