Vlada [557]

The hypothesis devised in this study by the researcher is –

" White fly nymphs escape predation because of their translucent bodies."

In order to test this hypothesis, the researcher is required to conduct an experiment where two sets of white fly nymphs are formed and fed to their predators. The two set of subjects would be -

Set I – White fly nymphs with translucent bodies

Set II- White fly nymphs with translucent bodies coated with harmless dyes.

The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.

Hence, option B is correct
