Criteria for Hypotheses construction are

1.It should describe one issue only.

2.It should describe many issues.

3.It should specify variables between which the relationship is to be established.

4.It should be specific and precise.

5.It should be empirically testable, whether it is right or wrong.

A1 only

B1, 2 & 3 only

C1, 3, 4 & 5 only ✓ Correct

D1, 2, 3 & 4 only

Correct answer: (C) 1, 3, 4 & 5 only

Explanation

A sound hypothesis describes only one issue, specifies the variables to be related, stays specific and precise, and remains empirically testable, so statements 1, 3, 4 and 5 hold.

Statement 2, that it should describe many issues, is wrong because a hypothesis must be narrow and focused on a single relationship.

Describing one issue only keeps the hypothesis clear and avoids confounding several relationships at once.

Specifying the variables makes the expected relationship explicit and directs the design.

Being specific and precise allows the hypothesis to be operationalised and measured.

Empirical testability means the hypothesis can be supported or refuted by observed data.
