Correct Answer: Option D — 300 microfarads

Total capacitance for parallel capacitors is calculated by the direct algebraic sum of individual values. Adding C1 (100 microfarads) and C2 (200 microfarads) yields a total parallel capacitance of 300 microfarads in accordance with standard AC circuit principles.
