Up a Triple Integral for the Volume of the Solid $z = 14 - x ^ { 2 }$

up a triple integral for the volume of the solid bounded above by the cylinder $z = 14 - x ^ { 2 }$ and below by the paraboloid $z = x ^ { 2 } + 15 y ^ { 2 }$ .

A)
$\int_{-\sqrt{7}}^{\sqrt{7}} \int_{-\sqrt{\frac{b-x^2}{a}}}^{\sqrt{\frac{b-x^2}{a}}} \int_{x^2+15y^2}^{14-x^2} d z dy d x$

B)
$\int_{-\sqrt{14}}^{\sqrt{7}} \int_{-\sqrt{\frac{b-x^2}{a}}}^{\sqrt{\frac{b-x^2}{a}}} \int_{14-x^2}^{x^2+15y^2} d z dy d x$

C)
$\int_{-\sqrt{14}}^{\sqrt{14}} \int_{-\sqrt{\frac{b-x^2}{a}}}^{\sqrt{\frac{b-x^2}{a}}} \int_{x^2+15y^2}^{14-x^2} = d z dx d y$

D)
$\int_{-\sqrt{7}}^{\sqrt{7}} \int_{-\sqrt{\frac{14-2x^2}{a}}}^{\sqrt{\frac{14-2x^2}{a}}} \int_{x^2+15y^2}^{14-x^2} = d z dy d x$


E)
$\int_{-\sqrt{7}}^{\sqrt{14}} \int_{-\sqrt{\frac{b-x^2}{a}}}^{\sqrt{\frac{b-x^2}{a}}} \int_{14-x^2}^{x^2+15y^2} = d z dy d x$
