Answer

To solve the problem of matching the items in Column I with their corresponding units in Column II, we will analyze each item step by step.

### Step-by-Step Solution:

1. **Moment of Inertia (A)**:
- The moment of inertia is a measure of an object's resistance to changes in its rotation and is represented by the unit \( \text{kg} \cdot \text{m}^2 \).
- Therefore, we match **A** with **(r) kg-metre²**.

2. **Surface Tension (B)**:
- Surface tension is defined as the force per unit length acting at the surface of a liquid. Its unit is \( \text{N/m} \) (newton per meter).
- Thus, we match **B** with **(s) newton/meter**.

3. **Angular Acceleration (C)**:
- Angular acceleration is the rate of change of angular velocity and is measured in \( \text{rad/s}^2 \) (radians per second squared).
- Hence, we match **C** with **(t) radian/sec²**.

4. **Coefficient of Viscosity (D)**:
- The coefficient of viscosity describes a fluid's resistance to flow and is expressed in units of \( \text{kg/(m·s)} \) (kilogram per meter per second).
- Therefore, we match **D** with **(q) kg/(metre-sec)**.

5. **Modulus of Elasticity (E)**:
- The modulus of elasticity measures a material's ability to deform elastically (i.e., non-permanently) when a force is applied. Its unit is \( \text{N/m²} \) (newton per square meter).
- Thus, we match **E** with **(p) newton/m²**.

### Final Matches:
- A → (r) kg-metre²
- B → (s) newton/meter
- C → (t) radian/sec²
- D → (q) kg/(metre-sec)
- E → (p) newton/m²
