Explanation:

- Entire means having all parts or being whole.

- Option 1: Equal means being the same in quantity, size, degree, or value, and does not relate to the idea of something being whole or incomplete.

- Option 2: Absolute indicates something being total or complete, which is similar, not opposite, to entire.

- Option 3: Complete is synonymous with entire, meaning having all necessary parts.

- Option 4: Partial means not complete or whole, and is the opposite of entire.

Thus, the most appropriate antonym for "entire" is Partial.
