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

* Gravitational waves are powerful ripples that originate in deep space and eventually pass through Earth.
* The Laser Interferometer Gravitational Wave Observatory (LIGO) is a physics study that began in 2002.
* LIGO's goal is to detect and analyze gravitational waves.
* LIGO uses a pair of massive gravitational wave detectors called interferometers that are thousands of miles apart.
* In 2015, for the first time in history, LIGO researchers detected a gravitational wave passing through Earth.

The student wants to present LIGO's aim and methodology. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Difficulty: Medium
A: 

In 2015, LIGO's massive interferometers detected a powerful ripple that originated in deep space and eventually passed through Earth.

B: 

Though the physics study LIGO began in 2002, its massive interferometers didn't detect a gravitational wave until 2015.

C: 

To achieve its aims, LIGO uses a pair of massive interferometers that are thousands of miles apart.

D: 

A physics study designed to detect and analyze gravitational waves, LIGO uses a pair of massive interferometers that are thousands of miles apart.
