To determine which of the given whole numbers corresponds to the number words "sixty-five," let's break it down step-by-step:

1. Understand the number words "sixty-five":
- "Sixty" refers to the number 60.
- "Five" refers to the number 5.

2. Combine the numbers:

By directly comparing the number 65:
