Which of the following stars is most likely to be red?

Answer 1

B) Star B - Main Sequence Stars

Step-by-step explanation:

Red stars have the lowest surface temperature. They are the coolest stars. On the graph, the point with the lowest surface temperature is Star B/Point B. Star B reaches about 2,500°C as its surface temperature, the rest of the points/stars are higher than that (the rest of the stars/points have a higher surface temperature).

I got it right on my Segment Exam. :)

Hope your test goes well! <3
