## **Core Concept**
The Employees' State Insurance (ESI) is a social security and health insurance scheme for Indian workers. It provides medical care and cash benefits in the case of sickness, maternity, and employment injury. The scheme involves contributions from both the employer and the employee.

## **Why the Correct Answer is Right**
In the ESI scheme, the employee contributes 0.75% of their wages, while the employer contributes 3.25%.

The specific percentages are defined under the ESI Act.

- **Option B:** This option suggests a 1% contribution, which is also incorrect for the same reason.
- **Option D:** This option suggests a 2.75% contribution, which is not the correct rate for employee contributions.
