The compression ratio is given by the ratio of volume before compression to volume after compression.
The expansion ratio is given by the ratio of the volume after expansion to the volume before expansion.
Hence, Compression ratio = Expansion ratio.
The expansion ratio is given by the ratio of the volume after expansion to the volume before expansion.
Hence, Compression ratio = Expansion ratio.

The Correct answer is option (A)
V1/V2 = r.
V1/V2 = r.

No, compression should be their instead of an expansion in the question or answer should be option A.

Why it is called expansion ratio?

Expansion and compression ratio are greater than one. So volume after expansion to volume before expansion.

Because it is the ratio of after expansion volume/before expansion.
