p=-g means that if p=-3 then g=+3 if p=π, then g=-π
bsically, if p is x units away from 0, G is x unit from zero on the other side of zero
lets see our options
A. P is 3 units away from 0 and G is 3 units on other side. correct
B. P is 3 units awy from zero and G is 0 units, not correct
C. P is 4 units away and G is 3 units, not correct
D. P is 0 units and G is 3 unit
answer is A
