At the end of your presentation, if it is appropriate for the type of presentation, solicit questions from the audience.
When someone is asking a question, make eye contact with that person, listen positively, and acknowledge by saying "thank you for that question," or say "that is an excellent question" or "that is an important question".
If the audience is in a large room and cannot hear each other's questions, repeat the question loudly for everyone to hear, before answering it.
If you know the answer to the question, respond appropriately and briefly so you can take more questions and not spend too much time on one question.

If the question is not relevant to the presentation, say something like, "I am really sorry that question is outside the scope of this presentation, but I will be happy to stay after the presentation and discuss it with you."

If time is running out for answering all of the questions, say, "I am sorry. I am running out of time, but I will take one last question, and then I will be available at the end to answer any remaining questions."
If you do not know the answer to a question say, "That is an interesting question, and I will have to get back to you later on that" or ask the audience "Can someone help me with this?" or be gracious and acknowledge you do not know the answer at that time.
If an audience member criticizes or attacks what you had covered in your presentation, do not attack back, but separate the valid criticism from the personal attack, and respond to the criticism appropriately.
