While researching a topic, a student has taken thefollowing notes:• In astronomy, the mass of stars can be describedin units called solar masses.• One solar mass is roughly equal to the mass ofthe Sun.• The mass of the star Proxima Centauri is0.122 solar masses.• The mass of the star Sirius A is 2.063 solar masses.The student wants to emphasize the mass of Sirius A.Which choice most effectively uses relevantinformation from the notes to accomplish this goal?A) The mass of stars, like Proxima Centauri, can bedescribed in units called solar masses.B) In astronomy, the mass of stars can be describedin units called solar masses, and one solar mass isroughly equal to the mass of the Sun.C) The Sun is more massive than Proxima Centauri,which has a mass of 0.122 solar masses.D) With a mass of 2.063 solar masses, Sirius A ismore massive than the Sun.
