it's not like sb to do/ to have done

[joham]

I ran across the following question:

---Mary said she was tired of studying English.
---It's not like her ______ like that.
A. to say anything B. to have said anything

I would think A is right. I wondered if we could also use B.

Thank you very much.

A is correct. There's nothing wrong with the grammar of B, but it implies that Mary's "good nature," if we can call it that, only lasted for a limited time in the past, rather than being a permanent quality.

"Mary smokes occasionally now, but while she was pregnant, she never touched a cigarette. She wouldn't have done anything to hurt the baby she was carrying."

"That's why I can't understand why she gives Johnny all that junk food. It's not like her to do anything to endanger his health."

Does that make sense?
