Match List-I with List-II. LIST-I (A) Coefficient of viscosity (B) Intensity of wave (C) Pressure gradient (D) Compressibility LIST-II (I) [ML^0T^-3] (II) ML^-2T^-2 (III) [M^-1LT^2] (IV) [ML^-1T^-1] Choose the correct answer from the options given below.

1. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
2. (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
3. (A)-(IV), (B)-(II), (C)-(I), (D)-(III)
4. (A)-(I), (B)-(IV), (C)-(II), (D)-(II)

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

Solution

The correct option matches each physical quantity with its appropriate dimensional formula: the coefficient of viscosity is expressed as [ML^-1T^-1], intensity of wave as [ML^0T^-3], pressure gradient as [ML^-2T^-2], and compressibility as [M^-1LT^2], accurately reflecting their definitions in physics.
