Answer:
Option C) PA and PB
Step-by-step explanation:
PA and ray PB are opposite because they are moving towards opposite direction and making an angle of 180 degrees.
On the other hand rays AP and BP are pointing toward each other.
AP and PZ are perpendicular to each other because they are making an angle of 90 degrees.
Whereas PW and PZ are making an angle of 45 degrees.

Sample size= n= 84
sample mean= x = 107 s
population standard deviation =σ= 11.7
As, population standard deviation is given so we use the estimate:
x(+/-) z(α/2)(σ/√n)
At 99% Confidence interval means significance level is α=1-0.99= 0.01
So,
α/2=0.005
Now, z at α/2=0.005
z= 2.576
Now, by putting values
107(+/-)((2.576)(11.7/√84))
( 107-((2.576)(11.7/√84)), 107+((2.576)(11.7/√84)) )
(103.7, 110.288)
