AValidity ✓ Correct
BReliability
CDependability
DSuitability
Correct answer: (A) Validity — Measuring the variable it is supposed to measure is validity, so that is the answer.
Explanation
★Measuring the variable it is supposed to measure is validity, so that is the answer.
★Validity means an instrument actually measures the thing it is meant to measure.
★So when a research truly captures the intended variable or dimension, it has validity.
★Reliability is about consistency of results, not whether the right thing is measured.
★Dependability is close to reliability, again not the match with the intended variable.
★Suitability is a loose term, so measuring the intended variable is validity.
