Problem
The diagram shows a circuit with four identical light bulbs.
[Figure: Circuit diagram showing 120V AC source connected to four identical light bulbs A, B, C, D arranged in a specific configuration]
When we remove bulb A from the circuit, the light intensity of bulb C:
(a) remains the same;
(b) increases;
(c) decreases;
(d) becomes zero.
