Modulus of Elasticity is dimensionally equivalent to:


ANSWER

Stress


SOLUTION
Modulus of elasticity $$=M^{1}L^{-1}T^{-2}$$
Stress $$=M^{1}L^{-1}T^{-2}$$
Surface tension $$=\dfrac{f}{l}=M^{1}L^{0}T^{-2}$$
Strain 
$$=\dfrac{\Delta L}{L}=M^{0}L^{0}T^{0}$$
Coeff of viscosity$$=F/A\dfrac{dv_{x}}{dx}=\dfrac{MLT^{-2}}{L^{2}\dfrac{LT^{-1}}{L}}=ML^{-1}T^{-1}$$
Hence, option A is correct.
