b. ΔH and ΔS are negative at all temperatures.

Explanation:

During the process of condensation,

The gaseous state convert to liquid state,

Hence, the entropy of the system reduces, i. e., the randomness decreases.

And the value for entropy is negative,

hence,

Δ S = negative,

Δ H = negative,

Since,

The heat is releasing from system.

hence, the most appropriate option will be ΔH and ΔS are negative at all temperatures.
