A hypothesis cannot be stated in

ANull form

BDeclarative form

CVague, general terms ✓ Correct

DDirectional form

Correct answer: (C) Vague, general terms

Explanation

A hypothesis cannot be stated in vague, general terms because it must be precise and testable.

Null form states no relationship or no difference between variables, a legitimate form.

Declarative form asserts a clear statement of expected relationship, fully acceptable.

Directional form predicts the specific direction of the relationship, also valid.

Vagueness blocks operational definition and measurement, so such wording is disqualified.

A workable hypothesis converts abstract ideas into observable, measurable variables.
