The correct answer is Option 4. In 1994, India achieved a significant milestone in space technology by demonstrating the capability to launch satellites into polar and near-geostationary orbits through the successful developmental flight of the Polar Satellite Launch Vehicle (PSLV-D2).

While India had already built satellites (Option 2) since Aryabhata (1975), the year 1994 was specifically transformative for her launch capability. The success of PSLV-D2 on October 15, 1994, which placed the IRS-P2 satellite into orbit, proved that India could independently deploy remote sensing and geostationary-class satellites. Other options are incorrect because:

• Option 1 & 3: India's ICBM warning systems and stealth missile technology were not the primary technological demonstrations of 1994; these are defense-specific developments that matured much later.
• Option 2: Satellite building was a capability established well before 1994.

Therefore, the 1994 breakthrough fundamentally centered on the indigenous launch vehicle technology required for geostationary and sun-synchronous orbits.
