Official Correct Choice:
Option B: 2 \(\Omega\)
Concept:

Conductance is defined as the mathematical reciprocal of resistance.

Formula:

$$ G = \frac{1}{R} \implies R = \frac{1}{G} $$

Solution:

  • Given Conductance \( G = 0.5 \text{ Siemens} \).


  • \( R = \frac{1}{0.5} = 2 \, \Omega \).


Why other options are incorrect:

  • Opt A, C, D: Mathematical errors when taking the reciprocal of 0.5.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
