b)
an experiment.

c)
survey research.

d)
correlational research.
b)
an experiment

Answer 1

Answer:

B. An EXPERIMENT

Explanation:

The research : trying to study 'Effect of Hunger on Taste Sensitivity'  is an Experiment based research - based on its special treatment (i.e depriving food for time intervals) on research participants in a controlled environment .

Although it tries to study relationship (correlation) between variables : Hunger & Taste Sensitivity , it doesn't do so without any control on either variable . Naturalistic Observation subject is also observed without any manipulation . So , it doesn't qualify to be either Naturalistic or Correlational Research . Survey Research includes getting participants responses through questionnaire , so it doesnt fit to this category as well .
