Correct Answer: Option A — 150 microfarads

Parallel capacitors combine additively, directly opposite to parallel resistors. Total capacitance is found by summing individual values (100 uF plus 50 uF), yielding 150 microfarads in accordance with standard electrostatic principles and IEEE 45 guidance.
