A network of four \( 9 \mu F \) capacitors is connected to a 500 V supply, as shown. In the context of this, identify the correct statements.

(A) \( C_4 \) is connected in parallel to the combination of \( C_1, C_2 \) and \( C_3 \).
(B) The equivalent capacitance of the combination \( C_1, C_2, C_3 \) and \( C_4 \) is \( 12 \mu F \).
(C) The charge on \( C_4 \) is \( 4.5 \times 10^{-3} \text{ C} \).
(D) The charge stored on \( C_1 \) and \( C_4 \) is the same.
Choose the correct answer from the options given below:

1. A (B), (C) and (D) only
2. B (A), (B) and (C) only
3. C (A), (C) and (D) only
4. D (A), (B), (C) and (D)
