False. There is no way for the act of stretching your neck to be imprinted into your genes; therefore, it is impossible for the length of the neck to be passed down to the next generation. The result of the length of a giraffe's neck was due to years upon years of natural selection favoring giraffes with longer necks.

Yes, but this an illustration of Lamarck's theory of inheritance, which was the theory before Dawin's theory of Evolution.

joefakes is right. Lamarck's theory doesn't take genetics into accout, because he lived before Mendel's theories of heredity. So he came to the conclusion that animals change themselves actively instead of the change caused by selection which was described by Darwin.

It is still a false theory. It explains the change, but not in the correct way
