The Mars Atmosphere and Volatile Evolution Mission (MAVEN) is a spacecraft launched by the United States of America (USA). This mission was initiated by NASA, which stands for the National Aeronautics and Space Administration. MAVEN is designed to study the Martian atmosphere and understand the processes that led to the loss of much of its atmosphere over time. It aims to gather data about the interactions between the Sun, the Martian atmosphere, and the solar wind.

Option 1 stating that MAVEN is a spacecraft launched by India is incorrect. It was not launched by India but by the USA.

Option 2 suggesting that MAVEN is a collaborative project of ISRO (Indian Space Research Organisation) and NASA is incorrect. While India and the USA have had collaborations in space exploration, MAVEN is solely a project of NASA.

Option 4 stating that MAVEN is a collaborative project of NASA and the European Space Agency (ESA) is also incorrect. There is no involvement of ESA in the MAVEN mission.

Therefore, the correct answer is option 3 - MAVEN is a spacecraft launched by the USA.
