	a	b	c
thickness	100 km	2000 km	millions of kilometers
temperature	5,500	6,000 to 20,000	2,000,000

what are the names of the suns layers described in columns a, b, and c?

a: corona; b: photosphere; c: chromosphere
a: core; b: chromosphere; c: photosphere
a: chromosphere; b: corona; c: core
a: photosphere; b: chromosphere; c: corona

Explanation:

1. The lowest atmospheric layer of the Sun is the Photosphere, with a thickness of ~100 km and a surface temperature of ~5,500°C, matching column A.
2. The middle atmospheric layer is the Chromosphere, ~2000 km thick with temperatures ranging 6,000 to 20,000°C, matching column B.
3. The outermost atmospheric layer is the Corona, extending millions of kilometers with temperatures reaching 2,000,000°C, matching column C.
