If each of the statements `p to ~q , ~ r to q` and `p` are true then which of the following is NOT true ?

A

`q` is false

B

`r` is true

C

`r to q` is false

D

`r^^~q` is false

Text Solution

Verified by Experts

The correct Answer is:
D
Since p is true and `p to ~q` is also true, therefore, `~q` is true. Also, since `~r to q` is true, `~r`is false and so, r is true. From above `r to q` is false.
