Explanation

First, find the story. Here is the funeral of a mean, judgmental man. The speaker respectfully finds nice things to say about him. For the first blank, look for things that go with arrogant and bitterly critical.

Only bellicose, meaning aggressive and hostile, is sufficiently negative. The second blank describes the actions of the guy, so we need something along the same lines.

Although eulogiesbelong at funerals, we need something bad. Diatribes work. The last sentence changes the direction by starting with nevertheless so we need something positive. Only magnanimous is positive.

Hence options B, D and G are correct!
