Let $\theta(x, y, z)$ be the statement “x+y=z” and let there be two quantification given as

- $\forall x \forall y \exists z \theta (x,y,z)$
- $\exists z \forall x \forall y \theta (x,y,z)$

where x, y, z are real numbers, then which one of the following is correct?

- I is true and II is true
- I is true and II is false
- I is false and II is true
- I is false and II is false
