Answer:
B) exothermic.
Explanation:
Hello!
In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.
In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:
B) exothermic

Explanation:
In a galvanic cell, the cathode is positively charged and the anode is negatively charged.
The cathode attracts electron while the anode donates or releases electrons.
Electrons received - Cathode
Electrons donated - Anode
