straightforward
meandering
energetic
transparent

Explanation:

The clue is that the audience was confused as the politician didn't address key - issues. "Straightforward" means clear and direct, which is the opposite of what's described. "Energetic" refers to having energy and has no relation to the lack of clarity. "Transparent" means easy to understand or see through, which is not the case here. "Meandering" means wandering aimlessly or not being direct, which fits the description of the politician's speech.

B. Meandering
