d) Compute $\int_{C} F \cdot d r$ where $\mathrm{C}$ is any curve from $(1,0,9)$ to $(1,2,2)$.

Step 1 ：The problem is incomplete. We cannot compute \(\int_{C} F \cdot d r\) without knowing the vector field F.

Step 2 ：Final Answer: \(\boxed{\text{The problem is incomplete. We cannot compute } \int_{C} F \cdot d r \text{ without knowing the vector field F.}}\)
