Solution

The correct option is A Longer lead is connected to positive terminal of the battery.
The longer lead of the LED is called anode and is the positive terminal, so should be connected to the positive terminal of the battery. Similarly, the shorter lead of the LED is called cathode and is negative terminal, so it is connected to the negative terminal of the battery.
