The physical quantities not having same dimensions are

1. torque and work
2. stress and Young's modulus
3. speed and (μ₀ε₀)^–1/2
4. momentum and Planck's constant

Answer

[Momentum] = [MLT^–1]

[Planck's constant] = [ML²T^–1]

Momentum and Planck's constant do not have same dimensions.

The correct option is D.
