and star b is a

Explanation:

To solve this, we analyze the characteristics of each star:

For Star A:

• Color: White
• Brightness: Relatively dim
• Temperature: Very high

White, hot, and dim stars are typically white dwarfs (they are hot but small in size, leading to lower brightness).

For Star B:

• Color: Red
• Brightness: Extremely bright
• Temperature: Low (compared to others)

Red, bright, and cool stars are typically red giants (they are large in size, so they appear bright despite lower temperature).

Answer:

Star A is a $\boldsymbol{\text{white dwarf}}$ and Star B is a $\boldsymbol{\text{red giant}}$
