Answer:
A. Passive approach
Explanation:
Why it's A: In an active approach (opposite to a passive approach), the speaker would mention what they do, how they do those things, etc. So in a speech, there would likely an active approach, not a passive approach.
In a passive approach, they may be welcoming, be more positevely emotional (such as showing you're happy, confident, etc. about the topic)
Why it's not C: The speaker would likely repeat many things to create emphasis on some idea.
Why it's not B or D: Typical speeches may be addressed to a more mature audience or a younger audience, so the level of language in speeches isn't a general convention.
