| i. | brightness of bulb \(C\) is highest. |
| ii. | if \(A\) fails, \(B\) will not glow. |
| iii. | if \(C\) fails, brightness of bulb \(D\) increases. |
| 1. | (i) only |
| 2. | (ii) only |
| 3. | (i) and (ii) only |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements choose the correct answer from the options given below:
| Assertion (A): | When an external resistor of resistance R (connected across a cell of internal resistance r) is varied power consumed by resistance R is maximum when R=r. |
| Reason (R): | Power consumed by a resistor of constant resistance R is maximum when the current through it is maximum. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
