Solution

The correct option is A

p~q


Explanation for correct option :

By the De Morgan's Law, we know that

(~p)(~q)=~(pq)

This means if there is a negation of p or negation of q then that will be equal to the negation of p and q.

Now, the required statement is that it is snowing and it is not that I am cold.

If it is snowing then there is no negation of p. Also, there is ‘and’ as the connector.

The second statement was that I am cold but here it is not that I am cold which means it is a negation of q.

From this, we can describe the required statement as p~q.

Hence, the correct option is (A).
