Answer:
50% of unpolarised light passes through the first filter because, on average, 50% of the waves are aligned with the fiter's axis. Intensity is reduced by a factor 0.5.
The second filter then reduces the intensity by a factor cos²(θ)
Explanation:
B IS YOUR ANSWER.
Soft sound has small amplitude and louder sound has large amplitude. Since, the second wave has large amplitude, it will have the loudest sound.
