<h3>
Answer:</h3>
d. One-shot case study
<h3>
Explanation:</h3>
The reason why answer choice "d. One-shot case study" would be the correct answer because this would be a experimental design that has the least, or fewest, explanatory power compared to the other experimental designs.
A one-shot case stud is a study where students do not use any controlling factors and use only a single test group. Only one measurement would be taken after the study. The only thing that a one-shot case study would be measuring is the post-test results.
A "explanatory power" is pretty much a theory or hypothesis that one could make about a given subject and explain the subject very well and what causes it.
A one-shot case study doesn't have many factors that would help support a theory or hypothesis, due to the lack of evidence it would provide. This is why a one-shot case study would have the least explanatory power.

The ocean energy Buoy is an oscillating water column tool that works through pumping air by means of the herbal upward thrust and fall of ocean waves through an air turbine machine to generate strength. ” The goals of the assessments “ include validating device durability within the open ocean environment, and measuring electricity output at full.
The buoys are submerged greater than a meter below the water's floor. internal, a cylinder that moves round a piston-like structure as the buoy bobs with the rise and fall of the waves. That movement drives a generator on the sea ground, generating energy, that's despatched to the shore along an underwater cable.
Closed-cycle structures use the sea's warm floor water to vaporize a working fluid, which has a low-boiling point, inclusive of ammonia. The vapor expands and turns a turbine. The turbine then turns on a generator to supply electricity.
