Replicate prove reliability and validity

Its the second one nonmetals are moldable and easily shaped 

The answer to your question would be c. mineral oil  

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
