B

Statement 1 is correct statement 2 is incorrect
C

Statement 1 is incorrect statement 2 is correct
D

Both statements 1 and 2 are incorrect

Solution

Resistance, $R = \frac{V^{2}}{P} \Rightarrow R \propto 1 / P$
i.e., higher is the wattage of a bulb, lesser is the resistance and so it will glow bright.
