Be Angry with sb. about sth. (for sth.)

[SongYuxiang]

Dear Native English-speaking teachers,

Would you please tell me which of the following two sentences is incorrect:

1) She was angry with him about keeing her waiting too long.
2) She was angry with him for keeing her waiting too long.

I really don't know because both sound correct to me. But I saw the answer in a text sheet showing only the first sentence is correct and the second sentence is incorrect. I have been confused.

Thank you in advance.

2. sounds more natural to me.
But you'd say, "She was angry about the wait", not " ... for the wait".
I am angry about something.
I am angry with (or at) someone for doing something.

No. 2 is correct
"for" explains the reason for being angry while "about" tells the thing or idea about which someone is angry.They cannot be used alternatively.
"I am angry with her for her misbehaviour"
