The Correct Option is C

Solution and Explanation

Step 1: Analyze the capacitor combination.
The five capacitors are arranged in series and parallel combinations. Let's assume the capacitors are in the following configuration: two capacitors in series and the result in parallel with the other three.
Step 2: Calculate the equivalent capacitance.
For capacitors in series, the equivalent capacitance \( C_s \) is given by: \[ \frac{1}{C_s} = \frac{1}{C} + \frac{1}{C} \] Thus, \( C_s = \frac{C}{2} \). For capacitors in parallel, the equivalent capacitance \( C_p \) is the sum of the individual capacitances: \[ C_p = C + C_s = C + \frac{C}{2} = \frac{3C}{2} \]
Step 3: Apply the result to the given total capacitance.
Given that the total capacitance is 2 \mu F: \[ \frac{3C}{2} = 2 \implies C = \frac{4}{3} \, \text{\mu F} \] Thus, the correct answer is (C) 10 \mu F.
