Answer 1

Key Points

List I	Explanation
Dimension of Torque	Torque is a measure of the rotational force applied to an object. Its dimension, ML2T-2, represents the combination of mass, length, and time.
Dimension of Impulse	Impulse refers to the change in momentum of an object due to a force acting on it. Its dimension, MLT-1, represents the combination of mass, length, and time.
Dimension of Pressure	Pressure is the force applied per unit area. Its dimension, M-1L3T-2, represents the combination of mass, length, and time in the inverse of mass, cubed length, and squared time.
Dimension of Gravitational Constant	The gravitational constant is a fundamental constant in physics that represents the strength of the gravitational force. Its dimension, ML-1T-2, represents the combination of mass, length, and time in the inverse of mass and squared time.

Hence the correct match is (a) - (ii), (b) - (iv), (c) - (i), (d) - (iii)
