The unit of moduluts of elasticity is :

Options

A. kg/(`"meter"^(2)`-second)
B. kg/(meter-`"second^(2)`)
C. kg/`("meter"^(2)-"second"^(2))`
D. `kg//"meter"^(3)`-second

Explanation

To find the unit of modulus of elasticity, we will follow these steps:

### Step 1: Understand Modulus of Elasticity
The modulus of elasticity, particularly Young's modulus, is defined as the ratio of stress to strain.

### Step 2: Define Stress and Strain
- **Stress** is defined as force per unit area. The formula for stress is:
\[
