Answer:
B. get smaller
Explanation:
The parallax angle of a star measured with respect to the Earth is inversely proportional to the distance of the star from the Earth:
where
is the parallax angle, measured in arcsec
d is the distance between the star and the Earth, measured in parsec
Therefore, if the star Alpha Centauri is moved farther from Earth, then d increases, and therefore the parallax angle will get smaller.
