a) Work done= Force * displacement and torque= force* perpendicular distance, so dimension of both are same

b) momentum = mv ,dimension is MLT^-1

energy E=h*frequency or dimension of h=ML^2T^-1

both dimensions are not same

d) speed of light $C=\frac{1}{\sqrt{\mu_0\epsilon_0}}$

c) youngs modulus = stress/strain

strain is dimensioless

so dimension of stress= dimension of youngs modulus
