Assertion (A): Alloys are commonly used ...

Assertion (A): Alloys are commonly used is electrical heating devices like electric iron and heater.
Reason ( R): Resistivity of an alloy is generally higher than that of its constituent metals but the alloy have lower melting point then their constituent metals.

A

Both (A) and (R ) are true and (R ) is correct explanation of the assertion

B

Both (A ) and ( R) are true but (R ) is not the correct explanation of the assertion.

C

(A ) is true but (R ) is false

D

(A) is false but (R ) is true
