ARecord haphazard behaviour with no plan

BSet up controlled experiments to uncover causal elements in behaviour

CSet out to actively observe subjects in their natural settings ✓ Correct

DInterview subjects at different stages of life

Correct answer: (C) Set out to actively observe subjects in their natural settings

Explanation

In naturalistic observation the researcher actively observes subjects in their own natural settings.

Recording haphazard behaviour with no plan is not naturalistic observation, which remains systematic.

Setting up controlled experiments to uncover causes describes the experimental method instead.

Interviewing subjects at different life stages describes a developmental or interview design, not observation.

Naturalistic observation avoids manipulation so that behaviour stays spontaneous and undisturbed.

Its main weakness is limited control, which weakens claims about cause and effect.
