"There is nobody in the living room.", is correct and should be accepted.

I feel gratitude towards those who invented Duolingo. During this bizarre period kept me busy while I learned four languages, including my Chinese, which I would not have taken them to such a level! Thank you!!

There is no people in the living room: this should work as well

"There are no people"

[LeiFeiRalf]

That's not correct English! You would use "are" for "no people" but that sounds strange too. It suggests you are emphasising no people but only animals.

A native speaker would say "there is nobody" (note that nobody is singular but no people is plural!)

[LeiFeiRalf]

Or "there is no one" as the answer uses.
