14. Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R) : Assertion (A) : the heating element of electric heater is made up alloys. Reason (R) : alloys have high resistivity and high melting point.

both A and R are true and R is the correct explanation of A


both A and R are true but R is not the correct explanation of A


A is true but R is false
