It is difficult for someone to do something...

Hello.

Would you take a look at the following?

1. It is difficult for her to answer this question.

2. For her to answer this question is difficult.

3. To answer this question is difficult for her.

Are these different in meaning? Or do they all have the same meaning?
If the meanings are different, would you explain the difference to me?

Thank you very much in advance for your help on this.

Hello.

Would you take a look at the following?

1. It is difficult for her to answer this question. Correct.

2. For her to answer this question is difficult. Messy! Though you could say "For her, answering this question is difficult."

3. To answer this question is difficult for her. "Answering this question is difficult for her."

Are these different in meaning? Or do they all have the same meaning?
If the meanings are different, would you explain the difference to me?

Thank you very much in advance for your help on this.

See above.

The amendments made above by emsr2d2 are good.
However, if you read these sentences somewhere, they would all mean the same thing.

Making a slight difference in the proposition:
1. It's always difficult for him to admit he's wrong.
2. For him to admit he is wrong is always difficult for him.
3. To admit he is wrong is always difficult for him.

These are all good. Sometimes "admitting" would be better than "to admit", but in situations like this, the meaning is the same.
