Which of the following are correct, with reference to Indian satellites and their launchers:

(A) All the INSAT series of satellites were launched abroad.

(B) PSLVs were used to launch IRS-series of satellites.

(C) India used the indigenously built cryogenic engines for the first time for powering the third stage of GSLV

(D) GSAT, launched in the year 2001, has payloads to demonstrate digital broadcast and internet services.

Choose the correct answer from the options given below:

In the original context of this question, statements (A), (B) and (D) were correct. At that time, INSAT-series satellites had been launched using foreign launch vehicles, PSLVs were used for IRS-series satellites, and India had not yet successfully flown an indigenously developed cryogenic upper stage on the GSLV. GSAT-1, launched in 2001, carried experimental payloads for services including digital broadcasting and internet communication.

In the present context, the situation has changed. India has since launched INSAT satellites using indigenous launch vehicles, and an indigenous cryogenic upper stage has also been successfully used on the GSLV. Therefore, today statements (B), (C) and (D) would be correct, but that combination is not available among the options. The original intended answer is therefore Option 1.
