I say d).......

Because the experimenter determines the experimental conditions. It is therefore 'Manipulated' by the researcher. It would be conducted in a Lab environmnent, hence being classed as a 'very controlled' research design.

a) is 'how' initial data is collected on the variables,
and anything 'field' is usually observational with no control of the experimenter, and it would be very hard to conduct a very controlled manipulated experiment(b), somewhere out in the Savannah!

cheers :-)

Research design is vital in planning for a reliable experiment based on a hypothesis, as inaccurate planning can lead to wrongly assuming that a correlation demonstrates a cause. Controlling the variables will ensure a higher level of accuracy and help you to reach a valid conclusion.
