For the solution of 2 0 u ∇ = , the domain and boundary conditions are shown below. Which of the following statements is TRUE?

- A. The solution cannot be obtained using separation of variables because the governing equation is non-separable.
- B. The solution cannot be obtained using separation of variables because all the boundary values are non-zero.
- C. The solution cannot be obtained using separation of variables because not all the boundaries are along constant coordinate lines.
- D. The solution can be obtained by separation of variables.
Answer: C. The solution cannot be obtained using separation of variables because not all the boundaries are along constant coordinate lines.
