(c) All the three

(d) None

Ans-c

Explanation

The Axiom-4 mission

The Axiom-4 mission a collaborative effort of Axiom Space, NASA, European Space Agency (ESA) and Indian Space Research Organisation (ISRO)

During the 14-day mission docked to the orbiting laboratory, the astronauts will conduct global outreach activities, microgravity research and technology demonstrations.

PSLV-C60 SpaDeX mission

SpaDeX mission is a cost-effective technology demonstrator mission for the demonstration of in-space docking using two small spacecraft launched by PSLV.

PS4-Orbital Experiment Module, designated as POEM, refers to the usage of the spent fourth stage of the Polar Synchronous Launch Vehicle (PSLV). It provides an opportunity for the scientific community to carry out certain in-orbit microgravity experiments for an extended duration of up to three months

PSLV-C60 SpaDeX mission is the fourth POEM Mission (in short POEM-4) in the series. 

Gaganyaan 

Indian Human Space Program, Gaganyaan aims to encourage and support Indian scientific community in microgravity research activities through flight opportunities in ISRO’s missions as well as joint international efforts.
