STATEMENT – 1: Compressibility factor for hydrogen varies with pressure having a positive slope at all pressures when at 273 K.
STATEMENT – 2: Even at low pressures, repulsive forces dominate in hydrogen gas at 273 K.

Solution
The correct option is A Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1
In the case of H2, compressibility factor increases with an increase in pressure. Even at 273 K, Z > 1 which shows that it is difficult to compress the gas when compared to an ideal gas. In this case, repulsive forces dominate.
