Answer 1

Correct answer is (a) Conjugate effect is stronger than (-I) effect

To explain I would say: Conjugate effect is stronger than (-I) effect. Conjugate effect (or delocalization) is an effect in which molecular orbitals (MOs) are conjugated to new molecular orbitals that are more delocalized and therefore generally lower in energy.
