Final Answer :
A
Explanation :
Validity refers to the extent to which a measurement tool accurately measures what it is supposed to measure. Internal reliability refers to the consistency of the measurement tool within itself. Test-retest reliability refers to the consistency of the measurement tool over time. Intercoder reliability refers to the consistency of the measurement tool between different coders or observers. Therefore, the best choice for a scale that measures what it is supposed to measure is validity.
