Explanation:

- The word "enthral" means to captivate or hold someone spellbound or fascinated. It's often used when something is so interesting or beautiful that it draws all attention.

- Option 1: Eject - This means to throw out or expel something from a place. It's often the opposite of captivating, as it involves removing rather than attracting.

- Option 2: Enchant - This means to delight or charm someone thoroughly, often through beauty or magic. It's closely related to enthralling because both involve captivating someone’s attention.

- Option 3: Repel - This is to drive back or ward off something. It is the opposite of enthralling because it implies causing distaste or aversion.

- Option 4: Incite - This means to stir up or encourage someone or something towards action. It doesn't relate to captivating someone through charm or interest like "enthral" does.
