### Circulation of a Circle in the Plane x + y + z = 4

A circle \(C\) in the plane \(x + y + z = 4\) has a radius of 3 and center \((3, -1, 2)\). Evaluate \(\oint_{C} \mathbf{F} \cdot d\mathbf{r}\) for \(\mathbf{F} = \langle 0, 2z, -y \rangle\), where \(C\) has counterclockwise orientation when viewed from above.

**Questions:**
1. Does the circulation depend on the radius of the circle?
2. Does it depend on the location of the center of the circle?

**Integral to evaluate:**
\[
\oint_{C} \mathbf{F} \cdot d\mathbf{r} = \boxed{ }
\]

(*Type an exact answer, using \(\pi\) as needed*)

**Does the circulation depend on the radius of the circle?**
- \( \circ \) A. Yes. The circulation is inversely proportional to the radius.
- \( \circ \) B. Yes. The circulation is proportional to the radius.
- \( \circ \) C. Yes. The circulation is proportional to the square of the radius.
- \( \circ \) D. No. The circulation does not change with the radius.
- \( \circ \) E. Yes. The circulation is inversely proportional to the square of the radius.

**Does the circulation depend on the location of the center of the circle?**
- \( \circ \) A. No. The circulation does not change when the circle moves in the plane.
- \( \circ \) B. Yes. The circulation has a complex relationship with the location of the circle.
- \( \circ \) C. Yes. The circulation changes linearly with \(y\).
- \( \circ \) D. Yes. The circulation changes linearly with \(z\).
- \( \circ \) E. Yes. The circulation changes linearly with \(x\).
