Explanation:

All the pairs are correctly matched

• Chandrayaan 2 was a follow-up to India's successful Chandrayaan 1 mission, and comprise of a orbiter, a lander (Vikram), and a rover (Pragyan).

• Chandrayaan-2 carried eight experiment payloads on board for studying surface geology, composition and exospheric measurements of Moon.

• Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS)

• Solar X-ray Monitor (XSM)

• CHandra’s Atmospheric Compositional Explorer 2 (CHACE 2)

• Dual Frequency Synthetic Aperture Radar (DFSAR)

• Imaging Infra-Red Spectrometer (IIRS)

• Terrain Mapping Camera (TMC 2)

• Orbiter High Resolution Camera (OHRC)

• Dual Frequency Radio Science (DFRS) Experiment

AstroSat is India’s first dedicated Space Astronomy Observatory launched into a 650-km, 6° inclination orbit.

• It has five advanced payloads

1. Ultra Violet Imaging Telescope (UVIT)
2. Large Area X-ray Proportional Counter (LAXPC)
3. Cadmium–Zinc–Telluride Imager (CZTI)
4. Soft X-ray Telescope (SXT)
5. Scanning Sky Monitor (SSM)

Mars Orbiter Mission (MOM), India's first interplanetary mission to planet Mars was launched onboard PSLV-C25 on November 05, 2013.

• the Indian Mars Orbiter Mission carried the following five scientific payloads:

1. Mars Color Camera (MCC)
2. Thermal Infrared Imaging Spectrometer (TIS)
3. Methane Sensor for Mars (MSM)
4. Mars Exospheric Neutral Composition Analyzer (MENCA)
5. Lyman Alpha Photometer (LAP)

• Aditya L1 is India’s first space mission to study Sun.
• It has four advanced payloads:

1. Visible Emission Line Coronagraph (VELC)
2. Solar Ultraviolet Imaging Telescope (SUIT)
3. Aditya Solar Wind Particle Experiment(ASPEX)
4. Plasma Analyzer Package for Aditya(PAPA)

Why in News?

• PAPA payload aboard Aditya-L1 detected solar wind impact of Coronal Mass Ejections.

Hence option 4th is correct.
