Select the most appropriate ANTONYM of the given word.
Tight

The correct answer is Slack.

Let us understand the meaning of the given word and the options to find the correct antonym (opposite word):

1. Tight: This word refers to something that is stretched, pulled, or kept taut, with no slack (e.g., a tight rope), or closely fitting.

2. Slack: This word means loose, not taut, or relaxed (e.g., a slack rope). Since it directly represents the state of not being tight or stretched, "Slack" is the perfect antonym of "Tight".

Let's also look at the other options to understand why they are not correct:
- Cordial: Means warm, friendly, or polite (e.g., a cordial greeting). It has no relation to "Tight".
- Comfortable: Means providing physical ease and relaxation. While tight things might be uncomfortable, the direct physical opposite of "tight" (in terms of tension) is "slack".
- Resilient: Means able to recoil or spring back into shape after bending, stretching, or being compressed. It refers to elasticity and durability rather than the opposite of tension.

Therefore, Slack is the most appropriate antonym for Tight.
