Answer 1

A

Step-by-step explanation:

A. They are cooler than the surrounding area of the Sun.

Sunspots are regions on the Sun's photosphere where the magnetic fields are extremely strong, inhibiting the convective flow of hot gas from the solar interior. These regions appear darker than the surrounding photosphere because they are cooler (around 3,500-4,500 K) than the surrounding areas (around 5,500 K), making them less luminous.
