Explanation:

- Linear Momentum is defined as the product of an object's mass and velocity. Its dimension is \( \text{[MLT}^{-1}\text{]} \).

- Work and Energy both share the dimension of \( \text{[ML}^2\text{T}^{-2}\text{]} \). They are measures of force applied over a distance and stored potential respectively, which differ from linear momentum.

- Impulse is the change in momentum and thus shares the same dimension as linear momentum, \( \text{[MLT}^{-1}\text{]} \).

- Stress is a measure of force per unit area and has the dimension \( \text{[ML}^{-1}\text{T}^{-2}\text{]} \).

Correct Answer: Option 3 - Impulse
