past or present?

There's another question.

Q: She has not come here yet. I am afraid she ( ) her way.
1. may be lost
2. may have lost
3. may be having lost
4. may have been lost

The book's answer is 2. may have lost., and it explains it's speculation about past.
This confuses me… Why is it past? She has not come here yet. means She's not here. Isn't it a present situation? Then why is speculation about present, 1. may be lost wrong?

The only possible answer is 2. Losing her way (a point event) happened in the past, though she presumably remains lost (a durational activity) at the moment.

Thank you Mister Micawber for answering my question!
With your explanation (with italic and underline!), now I totally understand why # 2 is the only correct choice!!! :)

Thanks again,
Kitty
