Correct answer is [B]. It is the ratio of volume at which fuel supply is cut-off to the clearance volume. In the Diesel cycle it is given by V3/V2.

C is the right answer. And cut off ratio is always less than one.
The cutoff ratio = 1/expansion ratio.

When the fuel ended in V3. Fuel injected from V2.
For IC Engine - V3_cut off point.
For IC Engine - V2_Clearence point.

Hence Option B is the correct one.
