Explanation:
A decreasing temperature indicates that the dissolution process for the ammonium chloride requires input of energy from surroundings. That is, the process is essentially 2 parts => system (object of interest - NH₄Cl) and the surroundings (everything else - solvent - H₂O). The surroundings (water) solvent is showing a <u>measured</u> decrease in temperature or loss of energy (exothermic to surroundings) which flows into the system (NH₄Cl) and effects dissolution of salt into solution (endothermic to system).

C. rusting is the correct answer
The higher the greenhouse gases, the higher the ocean temperature
"The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures"
hope this helps :)
