Cathode is the negative electrode and attracts positive charges. Which option reflects this statement?

Explanation:
Attracting opposite charges is the key idea. The cathode is the negative electrode, so it carries a negative charge and draws positively charged ions (cations) toward it. That makes the option describing a negative electrode that attracts cations the correct one. If the electrode were positive, it would attract negatively charged ions (anions), not cations, and a negative electrode attracting anions would be inconsistent with the charge–ion attraction rule. In this setup, the movement of cations toward the negative cathode best reflects how the system behaves.
