C Correct answer
Explanation

Ohms is correctly identified as the unit of electrical resistance, named after Georg Ohm who formulated Ohm's Law (V=IR). Newton measures force, Mhos (now called Siemens) measures conductance (the inverse of resistance), and Cadila is not a physical unit. Resistance is fundamental to electrical circuits and determines how much a material opposes current flow.
