Calculate the effective capacitance between points M and N.

A. 10μF
B. 5μF
C. 15μF
D. 7μF

To solve this question, we need to calculate the effective capacitance between points M and N. However, the problem doesn't provide a clear circuit diagram or information about the arrangement of capacitors. Without knowing how the capacitors are connected (whether in series or parallel), it's difficult to calculate the exact capacitance.

Here's how you would typically approach the problem based on different arrangements:

1. **Capacitors in Series**: The formula for the equivalent capacitance \( C_{\text{eq}} \) of capacitors in series is given by:

1 / \( C_{\text{eq}} = 1 / C_1 + 1 / C_2 + \dots + 1 / C_n \)

2. **Capacitors in Parallel**: The formula for the equivalent capacitance of capacitors in parallel is:

\( C_{\text{eq}} = C_1 + C_2 + \dots + C_n \)

To provide a solution, we need the circuit arrangement or additional details like the individual capacitances and how they are connected.

Could you clarify the configuration of the capacitors between M and N?
