Final answer:
Electrolytes can be acids, bases, or salts and can be either strong or weak electrolytes. All of the statements provided are true.
Step-by-step explanation:
The correct answer is (d) All of the statements are true.
Electrolytes are substances that dissolve in water to yield ions. They can be acids, bases, or salts. Aqueous solutions of acids are electrolytes, and they can be either strong electrolytes (100% ionized) or weak electrolytes (<100% ionized). Similarly, bases can also be electrolytes, and they can be either strong or weak. Electrolytes can be covalent compounds that chemically react with water to produce ions or ionic compounds that dissociate into cations and anions when dissolved in water.
