Match List I with List II and select the correct answer using the code given below the Lists : List I (Physical quantity) A. Distance B. Amount of material C. Amount of electrical charge D. Energy List II (Unit) 1. Mole 2. Coulomb 3. Light year 4. Watt hour Code : A B C D

The matching of physical quantities to their units is as follows: A. Distance is measured in light years, which is the distance light travels in one year. B. Amount of material (or substance) is measured in moles, an SI base unit defined by the Avogadro constant [2]. C. Amount of electrical charge is measured in coulombs (C), which represents the quantity of electricity [3]. D. Energy is measured in watt hours (Wh); while the joule is the standard SI unit, the watt hour is a common unit of energy derived from the product of power (watts) and time (hours) [2]. Therefore, the correct sequence is A-3, B-1, C-2, D-4, which corresponds to option 1.
