Terms associated with Sun	Description
1. Photosphere:	The visible outer layer of the sun
2. Chromosphere:	The the outer part of the atmosphere of the Sun
3. Sunspots:	Darker and cooler areas on the Photosphere

Which of the above pairs is/are correctly matched?

• A.
  1 and 2 only
• B.
  2 and 3 only
• C.
  1 and 3 only
• D.
  1, 2 and 3

Answer 1

The correct option is C

1 and 3 only

Explanation:

Pair 1 is correctly matched: Photosphere is the visible outer layer is called the photosphere. It has a temperature of around 6,000°C (11,000°F).

Pair 2 is incorrectly matched: Chromosphere is a layer placed above the photosphere and the solar energy passes through this while travelling out from the center of the Sun. It is not the outer part of the atmosphere of the Sun. The outer part of the atmosphere of the Sun is called Corona.

Pair 3 is correctly matched: Sunspots are darker and cooler areas (depressions) on the Photosphere, as compared to brighter and hotter regions of the photosphere around them on the photosphere, having a typical temperature of 4,000°C (7,000°F).
