If c denotes the contradication, then dual of the compound statement `~p ^^ (q vv c)` is

A

`~p vv (q ^^ t)`

B

`~p ^^ (q vv t)`

C

`p vv (~q vv t)`

D

`~pvv(q ^^ c)`

Text Solution

Verified by Experts

The correct Answer is:
A
For duality, replace `vv` by `^^` and `vv` by `vv` we get dual to the statement `~p ^^ (q vv c)`
`-=~ p vv (q ^^ t)`
