    var str1='<option value="AAA">AAA</option><option value="BBB">BBB</option><option value="CCC">CCC</option>',
    str2='<option value="CCC">CCC</option><option value="DDD">DDD</option>',

    result = str2.replace(/<option .+?<\/option>/g, function(m) {
        return (str1.indexOf(m) > -1)? "" : m;
    });

console.log(result); //returns <option value="DDD">DDD</option>

    (here I’m supposing you want to check for “atomic” substring <option>...</option>)
