Answer: D 

Solution: X + Y\rightarrow P

X and Y will combine to make a product P. X and Y are elements because they cannot be broken down into simpler substances. The product P is called compound and it will not have any property of elements X and Y.

The composition of elements in product will be fixed: If N moles of element X is present that means moles of element Y will be present. This product will be pure.

Hence statement (i), (iii) and (iv) are correct statements. Therefore the correct option of this question is option D.
