Mean  = 70 inches
= 70 inches
Standard deviation  = 3 inches
= 3 inches
Average basket ball player  = 79 inches
 = 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
