Correct Answer: 1

Solution : Given: $x^{2}+y^{2}+z^{2}=xy+yz+zx$
⇒ $x^{2}+y^{2}+z^{2}-xy-yz-zx=0$
⇒ $\frac{1}{2}[(x-y)^{2}+(y-z)^{2}+(z-x)^{2}]=0$
So, $(x-y)=0$, $(y-z)=0$, $(z-x)=0$
So, $x=y=z$
Putting this value in the given condition, we have:
$\frac{3x^{4}+7y^{4}+5z^{4}}{5x^{2}y^{2}+7y^{2}z^{2}+3z^{2}x^{2}}=\frac{15x^{4}}{15x^{4}}=1$
Hence, the correct answer is 1.
