To determine which of the given options is a **binomial**, we need to recall that a binomial is an algebraic expression consisting of exactly **two terms**.

Let's analyze each option:

**A. $$ 2x^{3} - 7y^{3} $$**
- This expression has **two terms**: $$ 2x^{3} $$ and $$ -7y^{3} $$.
- **Binomial**

**B. $$ x + 2y^{2} - 7 $$**
- This expression has **three terms**: $$ x $$, $$ 2y^{2} $$, and $$ -7 $$.
- **Not a binomial**

**C. $$ ab $$**
- This is a **single term**.
- **Not a binomial**

**D. $$ 5xy $$**
- This is also a **single term**.
- **Not a binomial**

**Conclusion:**  
**Option A** is the only binomial among the choices provided.

**Answer:**  
A. $$ 2 x^{3}-7 y^{3} $$
Option A is a binomial.
