Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Each bulb has a certain resistance. The line with two bulbs would have a larger resistance, as a result of which lesser current flows through that half of the circuit.
More current flows through the single bulb. The single bulb would hence glow brighter.
Both assertion and reason are true, and the reason is the correct explanation for the assertion.
