Question

When an electron-donating group ($+M$ effect) is attached to a benzene ring, it delocalizes electron density via resonance. This primarily increases the electron density at which specific positions on the ring?

Correct answer: C. Groups with a effect donate their lone pair electrons into the aromatic system. When you draw the canonical structures for such molecules (e.g., aniline or phenol), the formal negative charges strictly localize on the ortho and para positions, making these sites specifically nucleophilic and highly reactive toward electrophiles.
