Add restriction for selecting two contradictory response options in kobotoolbox

Hi, I want to add restriction in question for selecting two contradictory response options. For instance, I have a question “who uses the mosquito net in your house” and the options are 1. Children under five, 2. Elderly, 3. Pregnant women, 4. No one uses it, 5. Other.
I want to add a restriction if the enumerator selects any of the first three options, he or she could not select the option number 4 that is contradictory to the above options.
Keep in mind that I want to keep this question as select multiple options. Thanks in advance
