Correct answer: B. A-III, B-I, C-II, D-IV

(A) Young's modulus is stated as Y = (Stress)/(Strain) = ((F)/(A))/((∆ l)/(l)) = (Fl)/(A ∆ l) = [ MLT ^ - 2 ][L] [ L ^ 2 ][L] = [ ML ^ - 1 T ^ - 2 ] (B) Coefficient of viscosity is stated as η = (F)/(6 ) , here, v is velocity. (η) = [ MLT ^ - 2 ] [L][ LT ^ - 1 ] = [ ML ^ - 1 T ^ - 1 ] (C) Planck's Constant is stated as h = Energy Frequency = [ ML ^ 2 T ^ - 2 ] [ T ^ - 1 ] = [ ML ^ 2 T ^ - 1 ] (D) Work function has the same dimension as that of energy, so [ϕ] = [ ML ^ 2 T ^ - 2 ] Thus, A-III, B-I, C-II, D-IV
