The answer is option D
We can not predict it without knowing it's melting point.
Based on the boiling point and the current stable temperature, the state of this hydrocarbon would be c. Gas.
The boiling point of a substance is the temperature at which it becomes gas from gaining enough kinetic energy to evaporate into the air.
If the hydrocarbon in question boils at 0°C, this means that the hydrocarbon becomes gas at 0°C and remains at this state for every temperature above 0°C. At 250°C therefore, it would be gas.
In conclusion, option c is correct.
