Definitely, the answer is zero. It cannot be 1, because if 1 is inserted in an equation of efficiency of diesel cycle.
It becomes indeterminate numbers.

How can cut off ratio is less than 1? it can not be 0.

I am sure that the answer is definitely one.

The answer should be 1. Because cut off is zero and cut off ratio is 1.

Right answer is Option D, because cutt-off ratio equal to 1 put in equation then the efficiency of Diesel cycle approaches to Otto cycle efficiency.

Cut off ratio is the ratio of cylinder volumes after and before the combustion process. So, obviously, the ratio should be greater than zero.
When the cut-off ratio is 1 the efficiency of diesel cycle approaches to that of otyo cycle.
When the cut-off ratio is 1 the efficiency of diesel cycle approaches to that of otyo cycle.
