The correct answer is a Single pole, single throw (SPST), two position switch. This type of switch is commonly used for navigation lights in aircraft because it controls a single circuit with only an ON and OFF position.

Option A (Double pole, double throw (DPDT), three position switch) involves more connections and positions than necessary for a simple ON-OFF function.

Option C (Single pole, double throw (SPDT), three position switch) has an extra position that is not needed for the navigation lights control.

Option D (Double pole, single throw (DPST), two position switch) involves two poles, which is not required for the navigation lights operation.

Therefore, the most appropriate and efficient switch for controlling the navigation lights of some aircraft is a Single pole, single throw (SPST), two position switch.
