A binomial is defined as a polynomial that consists of exactly two terms.
Let's analyze the given options:
1. **x + 2y^2 - 7** - This has three terms, so it is not a binomial.
2. **ab** - This has one term, so it is not a binomial.
3. **2x^3 - 7y^3** - This has two terms, so it is a binomial.
4. **5xy** - This has one term, so it is not a binomial.
Based on this analysis, the binomial is:
**Answer: 2x^3 - 7y^3**
