The surface considered for Gauss's law is called

Options

A. Closed surface
B. Sphereical surface
C. Gaussian surface
D. Plane surface

Explanation

To solve the question regarding the surface considered for Gauss's law, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gauss's Law**: Gauss's law relates the electric field through a closed surface to the charge enclosed by that surface. It states that the electric flux through a closed surface is proportional to the charge enclosed within that surface.

2. **Identifying the Surface**: The surface used in Gauss's law must be a closed surface. This is essential because Gauss's law applies to the total charge enclosed by the surface.

3. **Types of Surfaces**: While there are various types of surfaces (like spherical, cylindrical, and planar), the specific term used in the context of Gauss's law is important.

4. **Defining Gaussian Surface**: The term "Gaussian surface" is specifically used to refer to any closed surface that we choose to apply Gauss's law. This can be a spherical surface around a point charge or a cylindrical surface around a line charge.

5. **Conclusion**: Based on the definitions and the context of Gauss's law, the surface considered for Gauss's law is called the "Gaussian surface."

### Final Answer:
The surface considered for Gauss's law is called a **Gaussian surface**.
