While researching a topic, a student has taken the following notes:

* Ducklings expend up to 62.8% less energy when swimming in a line behind their mother than when swimming alone.
* The physics behind this energy savings hasn't always been well understood.
* Naval architect Zhiming Yuan used computer simulations to study the effect of the mother duck's wake.
* The study revealed that ducklings are pushed in a forward direction by the wake's waves.
* Yuan determined this push reduces the effect of wave drag on the ducklings by 158%.

The student wants to present the study and its methodology. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Difficulty: Hard
A: 

A study revealed that ducklings, which expend up to 62.8% less energy when swimming in a line behind their mother, also experience 158% less drag.

B: 

Seeking to understand how ducklings swimming in a line behind their mother save energy, Zhiming Yuan used computer simulations to study the effect of the mother duck's wake.

C: 

Zhiming Yuan studied the physics behind the fact that by being pushed in a forward direction by waves, ducklings save energy.

D: 

Naval architect Zhiming Yuan discovered that ducklings are pushed in a forward direction by the waves of their mother's wake, reducing the effect of drag by 158%.
