Answer: C. 82.26%
Explanation:
Given : The red blood cell counts of women are normally distributed with


Let X be the random variable that represents the red blood cell counts of randomly selected woman.
Z-score : 
For X=4.2

For X=5.4

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.
Technically A and B, but A is more true, so it is the 'correct' answer.
