A surface enclosed an electric dipole, the flux through the surface is -

Explanation

To solve the problem regarding the electric flux through a surface enclosing an electric dipole, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Electric Dipole**:
An electric dipole consists of two equal and opposite charges, +q and -q, separated by a distance d. The net charge of the dipole is zero because the positive and negative charges cancel each other out.

2. **Identify the Surface Enclosing the Dipole**:
