Explanation:

- Loyalty: This is a strong feeling of support or allegiance. It implies a steadfastness in one's commitments or duties.

- Option 1: Hatred: This is a very strong feeling of dislike. It is the opposite of loyalty as it suggests negativity instead of allegiance or support.

- Option 2: Faithfulness: This suggests being true to one's word, promises, or vows. It closely aligns with loyalty as both involve staying committed and devoted.

- Option 3: Dislike: This refers to a mild form of not liking something. Like hatred, it does not fit as a synonym for loyalty because it conveys the absence of admiration or support.

- Option 4: Pleasure: This is the feeling of enjoyment or satisfaction. While positive in nature, it does not relate to loyalty, which is more about commitment rather than a sensation of happiness.
