Explanation:

To determine the galaxy's motion, we use the Doppler effect (redshift/blueshift). Redshift (light shifted to longer wavelengths, like right on the spectrum) means the source is moving away; blueshift (left shift) means moving toward. If the star's galaxy shows redshift (as hinted by "Right (redshift)" above), the galaxy is moving away from the Milky Way because redshift occurs when an object moves away, stretching light waves.

Answer:

The galaxy containing star C - 197 is moving away from our galaxy (the Milky Way). Explanation: The concept of redshift (where light from a moving object is shifted to longer wavelengths, often represented as a shift to the right in spectral analysis) indicates that the object is moving away from the observer. If the star’s galaxy shows a redshift (as suggested by the “Right (redshift)” label), this means the galaxy is moving away from the Milky Way as the light waves are stretched due to the galaxy’s motion away from us.
