Since the degree of freedom for the triple point is zero, it does not depend on any thermodynamic variables.

I think the triple point of any substance is at a specified temperature or pressure.
And if we change the pressure the triple will change.
Obliviously at triple point substance are independent at T&P.

So, the answer will be option D.

@Dhananjay.

The triple point is a function of the degree of freedom where F=0. Not a function of P and T.
