Final Answer :
B
Explanation :
Validity specifically addresses the question of whether a test, scale, instrument, etc. measures what it is supposed to measure. Reliability, on the other hand, refers to the consistency or stability of the measurements. While both reliability and validity are important considerations in measurement and assessment, only validity directly addresses the question posed.
