Explanation
Option B is incorrect because a CSTR is generally treated as a lumped parameter system, not a distributed parameter system. Proportional controllers are commonly used for level control (Option A). Distributed parameter methods indeed lead to partial differential equations (Option C). On-off controllers demonstrate non-linear characteristics (Option D).
