• A. p $△$ q $\square$ r
• B. p $\times$ q + r
• C. p $△$ q O r
• D. p O q + r

Answer 1

The correct option is C p $△$ q O r

In the question p × q ∅ r stands for p>q or p=q and q<r or q=r.

Option A- p is not equal to q then p may be greater than q and q<r. This is possible

Option B- p>q or p=q and q=r. This is possible.

Option C- p>q or p<q and q>r. This is not possible as q <r or q=r.
