The equivalent capacitance, C, due to C_1, C_2 and C_3 is

1. (A)\frac{1}{C_1 + C_2 + C_3}
2. (B)\frac{C_1 C_2 C_3}{C_1 + C_2 + C_3}
3. (C)\frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3}
4. (D)\frac{C_1 C_3 + C_2 C_3}{C_1 + C_2 + C_3}

This question uses a figure or table from the paper — you'll see it when you practise.
