A question born of worry: the fear not that your examiners won’t like something or agree with something, but simply that they won’t understand your research.
It’s unlikely your examiners would not understand your whole thesis, but possible that a detail or idea isn’t as clear as you think it is.
As with liking and agreeing, if there’s a problem of getting it then a good approach is to ask your examiners why. Ask why they don’t understand. Ask what the gap is. Ask where you lost them. The root “why?” invites more from your examiners. When you know what didn’t get across you’ll have an idea for what you might need to say.
Then speak. Engage, share, and help your examiners to see what you see in your research.
