{'gas dust': [0, 0, 1, 0], 'comet': [0, 1, 0, 2], 'bright ball': [0, 0, 1, 0], 'sky': [2, 1, 7, 11], 'constellation': [1, 0, 1, 2], 'star': [1, 1, 0, 0], 'galaxy': [0, 1, 0, 0], 'light': [16, 4, 34, 62], 'collection': [1, 0, 2, 1], 'tail': [0, 1, 2, 0]}

The correct answer is option 2: Comet. A comet is a collection of gas and dust that appears as a bright ball of light in the sky with a glowing tail.

Let`s review the other options to understand why they are not the correct answer:

1. Star: A star is a celestial object made up of hot gases that produces its own light and heat through nuclear reactions. It does not typically have a glowing tail like a comet.

3. Constellation: A constellation is a group of stars that appear to form a pattern in the sky. While constellations are made up of stars, they do not have the characteristics of a bright ball of light with a glowing tail like a comet.

4. Galaxy: A galaxy is a vast system of stars, gas, and dust held together by gravity. While galaxies can contain comets, a galaxy by itself does not appear as a bright ball of light in the sky with a glowing tail.

In conclusion, a collection of gas and dust that appears as a bright ball of light in the sky with a glowing tail is called a comet.
