Match the research feature in List I with its basic point in List II and choose the correct answer from the code given below:

Reliability pairs with stable, consistent and dependable, validity with the entities and devices used to measure the dimensions studied, intuition with constantly thinking about the research process, and objectivity with any personal bias vitiating results, giving i-d, ii-a, iii-b, iv-c.

Reliability (i) means results are stable, consistent and dependable, matching d.

Validity (ii) concerns whether the instruments truly measure the intended dimensions, matching a.

Intuition (iii) is the constant reflective thinking about the research process, matching b.

Objectivity (iv) requires that personal bias not distort the findings, matching c.

Reliability is necessary but not sufficient for validity.
