how to solve this

Question

hi
i tried to solve this and seems not to work

Answer 1

var par= document.getElementById("par");
var node= document.getElementById ("node");
par.removeChild.(node);

Answer 2

var par= document.getElementById("par");
var node= document.getElementById ("node");
par.removeChild(node);

Answer 3

In code you have dot after removeChild on the third line. That is wrong. Anyway 'node' have to be child of 'par'...

Answer 4

var par= document.getElementById("par");
var node= document.getElementById ("node");
par.removeChild.(node);

this is actually the correct answer
