Well this is my trying in D, I upload picture that show one of what I think can be an chiral carbon but I am not sure about the bond in the right side of it.

So D is also a Optical activity molecule?

Thanks.

The other chiral carbon that I think is carbon that have bond with 1(H) 2(OH) 3(COOH) for the bond from the left side here I not sure like in the carbon in the picture.

Yes, that's exactly it! Well done! :)

The C in the middle of your picture, AND the C just right of it are chiral.

OK thanks, but look at the picture to what atoms the right bond need to be?
And so I can say that D is also a Optical activity molecule?

Yes, it is.

To the right, you put CH(OH)COOH

For the next carbon atom, to the left you have HOOCCH(Br)

Well all I left to do is to thanks to you and drbob really thanks.
