Final answer:
Brent's action of seeking Allison's input on his proposal before the meeting is an example of the consultation influence tactic, aimed at incorporating her ideas and gaining her support.
Step-by-step explanation:
Brent is employing the consultation influence tactic when he brings his proposal to Allison before the meeting. By doing so, he's suggesting that Allison's ideas are valuable and that he is willing to incorporate her suggestions into his proposal.
