It offers me only אמא, מה נשמע as a right solution. But here in discuss the translate is diferent. Is it only other way how to say it?
How do you pronounce it?
אמא, מה שלומך?
Was marked incorrect
Don't bother to use punctuation marks - DL will accept anything without them (i.e., as long as the wording is correct)
i just put that in without the punctuation and it was accepted
Would it be proper to say "?אמא מה קרה" (What is the situation?/What's up?) instead?
Almost - you need the present of מה קורה. Your sentence means "Mom, what happened?" You could also use מה המצב which literally means "What's the situation?"
It's sort of like in English - if you ask it past tense (what happened) it sounds like there is something wrong .. Same for מה קרה?
אמא, מה שלומך? Is not one of the choices, please fix it
That is the default answer! It's not possible they rejected it. Maybe you made a mistake you didn't notice.
