I disagree totally with myschool admin saying that conception is the right answer, look, conception means act of conceiving a child/ time inwhich a child is conceived but scientist affirmed that s*x of a child is unknow until its between six to eight weeks of pregnancy, which means, it is never at conception. The answer should be at birth

It is set at conception.t he female contributes x and the male can contribute either x or Y. this therefore determine the s*x of the child.
They say it's unknown because they is no way of telling in scan since the s*x organ isn't dev.

Myschool is correct, the question says s*x(meaning gender) not s*x organs. the s*x of an individual is 'set' or determined during conception
