AValidity ✓ Correct

BReliability

CDependability

DSuitability

Correct answer: (A) Validity

Explanation

Validity is the term describing when research measures the variable or dimension it is supposed to measure.

Reliability instead refers to the consistency and repeatability of the measurement.

Dependability is a term from qualitative rigour paralleling reliability, not this idea.

Suitability is a general fit judgement, not the technical term for correct measurement.

Validity ensures the instrument targets the intended construct accurately.

Without validity, precise but wrongly aimed measurement is worthless.
