A scientist might repeat an experiment B) to check their own work in a previous experiment.

The results of an experiment must be reproducible. It is better for the scientists to do this themselves rather than have other scientists show they were wrong.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

i would say b

explanation:

but i think i would need more information than that
