Answer:
Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure
Explanation:
AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.
Hence, option C is correct
Hi,
The answer is none of them.

I personally, would remove " Lamp oil is a very polar substance " And replace it with what the article you wrote, was about. For example, lets say you wrote about why people love ice cream, you could have the ending sentence say. " And that's why I wrote about why people love ice cream" Or something along those lines. I'd write a few more facts about it first, don't just have one sentence saying a fact without any supporting detail, hope this helps! :)
