(D) for me

A number included in a standard deviation is included betwen (average - deviation) and (average + deviation).

Therefore here, we have 99,7 and 10,3. Then, we count all numbers between those 2 limits.

o 9,9 : 3 numbers
o 10 : 1 number
o 10,2 : 2 numbers

So,
Purcentage = 6/8*100 = 75

So this is about 1 Standard Deviation of the Mean. I follow that.
