Answer:

#D.#

Explanation:

In each Option, the L.H.S. is #6/8={(3)(2)}/{(4)(2)}=3/4.#

Now, in #A," the R.H.S."=51/68={(17)(3)}/{(17)(4)}=3/4.#

In #B, "the R.H.S.="39/52={(13)(3)}/{(13)(4)}=3/4.#

In #C," the R.H.S.="21/28={(7)(3)}/{(7)(4)}=3/4.#

In #D," the R.H.S.="15/24={(3)(5)}/{(3)(8)}=3/8.#

So, #D# is not a true proportion.
