AExperimental control

BA hypothesis ✓ Correct

CAn experimental variable

DA theory

Correct answer: (B) A hypothesis

Explanation

An educated guess about what is controlling some behaviour is called a hypothesis.

Experimental control refers to holding extraneous variables constant, not a guess.

An experimental variable is a factor being studied, not a tentative statement.

A theory is a broad, well-tested explanatory framework, far wider than a single guess.

A hypothesis is a tentative, testable prediction awaiting evidence.

It is verified or refuted through systematic empirical study.
