Answer:
B. One of the populations is normally distributed.
Step-by-step explanation:

Randomness : Data must not be biased as such it must be drawn as a random sample from a larger group.
The data must be independent. That is not related to one another, the outcome of one should not rely on the outcome or value of another.
Both groups must be drawn From a population which is normally distributed.
One group being normally distributed by stribuyed while the other isn't a requirement for hypothesis testing in this scenario.
Surface area is 4piR^2
Volume is 4/3 piR^3
R is the radius (half the diameter). Just plug in the numbers
