Then washers are made by which one Compound die or progressive die.

The answer is compound die.

Compound die is also a right answer.

In progressive die, two or more operations can be performed only at the different stage or different stroke of the ram.

But in compound die the two or more cutting operations are performed at a single stage or single stroke of the ram.

Whereas in combination die the two or more cutting and non-cutting operations are performed at a single stage or a single stroke of the ram.

In question, it is mentioned that two or more OPERATIONS (may be cutting: ex. Punching OR non-cutting: ex. Coining/embossing, bending) can be performed.

This is possible only in a progressive die. So I think answer B is the correct answer.

Yeah, correct @Rahul.

Incorrect question, Progressive, combination, compound dies all are the correct options, because in progressive different operations are done at different stages while in compound die mutli cutting operation are done at same stage and in combination die both cutting and non cutting operations are done at same stage on single stroke of ram.
