उत्तर
Both A and R are true but R is not the correct explanation of A.
Explanation:
The assertion is true because alloys such as nichrome are used in heating devices. The reason is also true as a general property of alloys, but it does not correctly explain the choice for heating elements, which require high resistance and high melting point.
