a)replicate research
b)solve a developmental problem
c)generate a discovery
d)change the behavior of many people
generate a discovery

Generate a discovery

Explanation:

Hannah's research generated the discovery that participants who got more sleep were safer drivers. The discovery was done by manipulating the participants' sleep patterns. She then tested their driving ability.

She did not replicate any research as the research was only hers, neither did she solve a developmental problem nor changed  the behavior of  many people. She simply stated a fact based on the results of her research and it's up to individuals to put the conclusions of the test into practise.
