Question

Quizplus · Accepted Answer

The polarization of light passing through the dust grains shows that the dust grains are elongated in shape and are aligned by a weak interstellar magnetic field. The polarization does not provide any evidence for the dust grains being chiefly made of iron. Therefore, both A and B are correct, but C is not. The polarization of light passing through the dust grains indicates that the grains are elongated in shape, which is option A. Additionally, the polarization patterns suggest that the dust grains are being aligned by a weak interstellar magnetic field, which is option B. Therefore, option D, which includes both A and B, is the correct answer. Option C, which suggests that the dust grains are chiefly made of iron, is not supported by the polarization data.
