If temperature of the system remains constant during the course of change, the change is

Options

A. Isothermal
B. Adiabatic
C. Isobaric
D. Isochroic

Explanation

To solve the question, we need to identify the type of thermodynamic process in which the temperature of the system remains constant during the course of change.

### Step-by-Step Solution:

1. **Understanding the Options**: We have four options to consider: isothermal, adiabatic, isobaric, and isochoric. Each of these terms describes a different thermodynamic process.

2. **Defining Isothermal Process**:
- An isothermal process is defined as a process in which the temperature of the system remains constant throughout the entire process.
