Answer:
The correct answer is D.They have stars that may appear to wobble.
Explanation:
Binary star - Wikipediaen.wikipedia.org › wiki › Binary_star
''Astronomers have discovered some stars that seemingly orbit around an empty space. Astrometric binaries are relatively nearby stars which can be seen to wobble around a point in space, with no visible companion. The same mathematics used for ordinary binaries can be applied to infer the mass of the missing companion''

The answer to the question is C
The statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.
<h3>What are intermolecular forces?</h3>
The term intermolecular forces are the force that hold matter together in a particular state such as solid liquid or gas. The more the electrons present, the greater the polarizability and the greater dispersion forces at work.
Thus, the statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.
