Correct answer: D. (iii) (iv) (i) (ii)

(1) Planck's constant aligned [h] & =[(E)/(v)] & = [ML^2 T^ -2 ] [T^ -1 ] =[ML^2 T^ -1 ] aligned (2) Gravitational constant aligned [G] & =[(F r^2)/(m_1 m_2)] & = [MLT^ -2 ][L^2] [M^2] & =[M^ -1 L^3 T^ -2 ] aligned (3) Bulk modulus aligned [B] & = [ Normal stress ] [ Volumetric strain ] & =[ML^ -1 T^ -2 ] aligned (4) Coefficient of viscosity, aligned & =([F])/([A][d v / d y])= [ML^ -2 ][L] [L^2][LT^ -1 ] & =[ML^ -1 T^ -1 ] aligned Hence, option (d) is correct.
