.hide() is not a function error when executing from a loop

I want to be able to loop over a few different labels and hide their content based on if a radio button is check or not. This is the solution I came up with, but I keep getting an error in the console.

var hazardOptions = $(".js-hazardous-option");
var hazard = $("input[name=Hazardous]");
for (var i = 0, len = hazard.length; i < len; i++) {
    if (hazard[i].id === "HazardousYes" && hazard[i].checked) {
        for (var ii = 0, length = hazardOptions.length; ii < length; ii++) {
            hazardOptions[ii].show();
        }
    } else if (hazard[i].id === "HazardousNo" && hazard[i].checked) {
        for (var iii = 0, leng = hazardOptions.length; iii < leng; iii++) {
            hazardOptions[iii].hide();
        }
    }
}

The error I get is:

hide() is not a function

Not sure what I'm missing, I've tried having a look online for a similar issue, but with no luck. I'm pretty sure that the problem is here: hazardOptions[iii].hide(); but not really sure why and/or how to fix it.
