Claim for real property tax relief credit. The third question makes no sense

The third question says was any rent you received for non residential use of your property 20% or less of your rental income during 2021.

 

The two choices are yes non residential Rep made up less than 20% of my rental income or no non residential rent was 20% or more of my rental income

 

the correct answer since I have zero rental income but that's not a choice, so how does one proceed here
