He usually tends to___________ any proposal I put forward during meetings.

Explanation

Option A, 'disagree,' fits best in the sentence: 'He usually tends to disagree with any proposal I put forward during meetings.' The word 'disagree' means to hold a different opinion, which aligns with the context suggesting he often opposes suggestions. The other options—consent, embrace, and collaborate—imply agreement or cooperation, which contradicts the intended meaning.
