Answer 1

When carbon disulphide is added to a cooled mixture of iron and sulphur, then no observational changes take place.

On the other hand, if carbon disulphide would have been added to a heated mixture of iron and sulphur then some drastic and noticeable changes would have taken place.

Thus, according to the question, the correct option is c) no reaction takes place.
