Which method does the Kepler Mission use to detect extrasolar planets?
A. Astrometric
B. Doppler
C. Transit
D. All of the above

The Kepler Mission primarily uses the Transit method to detect extrasolar planets by observing brightness dips in stars. Although the mission's data can also be useful for Astrometric and Doppler methods, it does not primarily employ these techniques. Therefore, the correct answer is that the Kepler Mission focuses mainly on the Transit method. ;
