Given the options the correct one is option "a" - By measuring a change in brightness of a star as a planet passes in front of it.

Explanation:

Kepler Telescope launched by NASA in 2009 uses sensors to monitor the brightness of more than 150,000 stars at the same time, in this way they can detect orbiting planets.
