Given below are two statements, one is labelled as Assertion and the other is labelled as Reason
Assertion (A): The disadvantage of atomic absorption spectroscopy is the need for each element to be analysed. 
Reason (R): As atomic absorption spectrophotometer uses different halocathode lamp for each element, it is very specific for an individual element under test.
