<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.
This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.
It does not affect the concentration of the reactants.
For the given reaction:

If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is 
Hence, the correct answer is Option A.

Explanation:
positive is helps to the right and wrong way
Correct Answer: Cation -A
Given that both the cations, cation-A and cation -B have the same concentrations.
Charge on cation-A is +3, while charge on cation- B is +1. Cations with higher charge can easily substitute those present on the clay minerals. Cations with higher charge have a greater affinity for the negatively charged sites present on the clay mineral. So, cation -A with a charge of +3 is more likely to occupy the anionic sites on the clay mineral.
