• A. a litres of A combines with b litres of B to give C and D under same P and T.
• B. a moles of A combines with b moles of B to give C and D.
• C. a g of A combines with b g of B to give C and D.
• D. a molecules of A combines with b molecules of B to give C and D.

Answer 1

The correct option is C a g of A combines with b g of B to give C and D.
