Solution

The correct option is C Statement I is true; Statement II is false.
Statement I is true; Statement II is false.
F atom has slightly lower affinity for the electron than chlorine.
It is due to the reason that additional electrons are repelled more effectively by 2p-electrons in F than by 3 p-electrons in Cl-atom.
