The correct answer is (a) Both assertion and reason are correct and reason is correct explanation of assertion.
The assertion that the catalytic activity for hydrogenation reactions increases from group-5 to group-11 metals with maximum activity being shown by groups 7-9 elements is true. These elements, including iron, cobalt, and nickel, are often used as catalysts for hydrogenation reactions because they have a high affinity for hydrogen and can facilitate the addition of hydrogen to unsaturated compounds.

The reason given for this phenomenon, that the adsorption rate is maximum for 7-9 group elements, is also correct. Adsorption is the process by which atoms, ions, or molecules from a gas, liquid, or dissolved solid are attracted and held onto a surface. During a hydrogenation reaction, the catalysts must adsorb hydrogen atoms onto their surface in order to facilitate the reaction. The high adsorption rate of 7-9 group elements means that they are able to adsorb a large number of hydrogen atoms, which increases their catalytic activity.

Therefore, both the assertion and the reason are correct, and the reason is a correct explanation of the assertion.
