Explanation / Answer

Hydrogenation is the reaction in which a molecule having at leat 1 double or triple bond is reacted with H2 in order to remove this double or triple bond by substituting hyderogen. Now in our molecule we observe that there is only 1 double bond. To remove 1 double bond we need 2 Hydrogen atoms that is 1 H2 molecule. So we need 1 mole H2 per mole of given molecule.

So, Ans: (a) 1 mol
