364667 A boy of height \(1.5\,m\) with his eye level at \(1.4\,m\) stands before a plane mirror of length \(0.75\,m\) fixed on the wall. The height of the lower edge of the mirror above the floor is \(0.8\,m\). Then :

1 The boy will see his full image.
2 The boy cannot see his hair.
3 The boy cannot see his feet.
4 The boy cannot see neither his hair nor his feet.
