Statement 1: Below its Boyle temperature, a real gas initially shows a negative slope in the Z vs P plot (Z dips below 1).
Statement 2: Below the Boyle temperature, attractive forces dominate at low pressures and pull the molecules closer, lowering Z below 1.

Statement I is correct: for T < T B , the Z vs P curve starts with a negative slope. Statement II is correct and is the cause: below T B attractions win at low P, the gas is more compressible than ideal, so Z < 1 and falls initially. II explains I. Ans: (a).
