Correct answer
Cq

Step-by-step explanation

Given prp~q~p

Assuming all option one by one,

Taking r=p

p q ~p ~q pp p~q prp~q
T T F F T F F
T F F T T T T
F T T F F F T
F F T T F F T

Now taking r=~p

p q ~p ~q p~p p~q prp~q
T T F F F F T
T F F T F T F
F T T F F F T
F F T T F F T

Taking r=q

p q ~p ~q pq p~q prp~q
T T F F T F F
T F F T F T F
F T T F F F T
F F T T F F T

So clear, prp~q~p
