If p,q and r are simple propositions such that `(p^^q)^^(q^^r)` is true, then

A

p,q and r are all false

B

p,q and r are all true

C

p,qare true and r is false

D

p is true and q, r are false

Text Solution

Verified by Experts

The correct Answer is:
B
`(p^^q) ^^(q^^r)` is true which means that `p^^q` and `q^^r` are both true.
Therefore, p,q and r are all true,.
