• B. Lunar Laser Ranging Instrument (LLRI) covered just the Lunar Poles and no other regions.
• C. Solar flares were detected by CIXS.
• D. It was India’s second unmanned lunar probe.

Answer 1

The correct option is C

Solar flares were detected by CIXS.

Chandrayaan, India’s $1^{st}$ unmanned lunar probe, carried payloads from Indian Space Research Organization (ISRO), National Aeronautics and Space Administration (NASA), Bulgarian Aerospace Agency (BAA), and European Space Agency’s (ESA). The Lunar Laser Ranging Instrument (LLRI) covered both the lunar poles and additional lunar regions of interest. European Space Agency payload-Chandrayaan-1 imaging X-ray spectrometer (CIXS) detected more than two dozen weak solar flares during the mission.
