In a polytropic process described by the equation $pv^n = C$, when $n = 0$, it represents an isobaric process (constant pressure). However, the question asks for $n = \pm ?$, which seems to be a typographical error because specific values of $n$ correspond to different types of processes. For instance, $n = 1$ represents an isothermal process, $n = \gamma$ (where $\gamma$ is the specific heat ratio) represents an isentropic process, $n = \infty$ (or a very high value) represents an isochoric process (constant volume), and there's no specific $n$ value that directly corresponds to a throttling process since throttling is an isenthalpic process, not described by the polytropic equation. Given the options and the context, the closest correct interpretation would be that $n = \infty$ (or a conceptual equivalent to $\pm ?$ if considering $\pm \infty$ as a broad, non-specific indicator) points to an isochoric process, where volume remains constant.
