Explanation:

You can solve this by assuming values of x, y and z.

Let the three numbers be 1, 3 & 5. 

Option (a) is 1² 3² 5² = 225, which is odd. 

Option (b) is 3(1² + 3³)5² = 2100, which is even. 

Option (c) is 5 + 3 + 5⁴ = 633, which is odd. 

Option (d) is $5^2\frac{(14+34)}{2}=$ 1025, which is not even and hence, the answer.

Hence, option (d).
