Answer: Option 4

An adiabatic process is represented by $$p{v^\gamma } = {\text{constant}}$$    now by replacing the $$p$$ with $$\frac{{nRT}}{v}$$   we get $$T{V^{\gamma - 1}} = {\text{constant}}$$    and by replacing the $$V$$ with $$\frac{{nRT}}{P}$$  we get the equation $${P^{1 - \gamma }}{T^\gamma } = {\text{constant}}.$$
