Solution

The correct option is D Statement-1 is false and Statement-2 is false.
Statement-1: Ortho hydrogen is favoured at all temperatures. From room temperature to very high temperature, the ratio of ortho to para hydrogen is 3:1.
Statement-2: The thermal conductivity of para hydrogen is about 50% greater than of ortho hydrogen.

Both statement-1 and Statement-2 are false.
