Answer 1

The Correct Option is A

Let's examine each of the options to determine if it is a satellite launched by India:
Explorer: The Explorer program was a series of over 90 United States spacecraft launched from 1958 to 2015. Explorer 1 was the first artificial satellite launched by the United States.
APPLE (Ariane Passenger Payload Experiment): APPLE was India's first experimental communication satellite, launched by the European Space Agency's Ariane rocket in 198(A) It was a significant step in India's space program.
Bhaskar: The Bhaskar series consisted of two low-orbit experimental remote sensing satellites launched by India in 1979 and 198(A) They provided valuable data for earth observation.
INSAT (Indian National Satellite System): INSAT is a series of multipurpose geostationary satellites launched by India for telecommunications, broadcasting, meteorology, and search and rescue operations. The INSAT system is one of the largest domestic communication satellite systems in the Asia-Pacific region. Therefore, Explorer is not a satellite launched by India; it is a program of the United States.
