Final answer:
A good elevator pitch should be 30 seconds long, tailored to the audience, practiced out loud, and delivered with confidence (B). Feedback can further refine the pitch, accompanied by a follow-up plan.
Step-by-step explanation:
The ideal length for a good elevator pitch should be 30 seconds. An elevator pitch is a quick, concise way to introduce yourself and share your professional background or business idea with potential employers or clients. It is important to keep it concise, as this should be enough time to articulate your message without losing the listener's attention.
Customize your pitch to your audience, practice it out loud, and be confident in your delivery. Seeking feedback from a career counselor or professional contact can also be very helpful. Remember to have a follow-up plan after delivering your elevator pitch.
