Explanation
The chronological sequence of these international technological milestones begins with the advent of Inter-Continental Ballistic Missiles (ICBMs). The first successful ICBM, the Soviet R-7 Semyorka, was launched in 1957. This was followed by the launch of the first communication satellite. While passive satellites like Echo 1 launched in 1960, Telstar 1, the first active communication satellite, was launched in 1962. India's own communication satellite journey began later, with the launch of APPLE in 1981 . Finally, the World Wide Web (WWW) was introduced by Tim Berners-Lee at CERN, with the proposal written in 1989 and the first web browser released to the public in 1991. Therefore, the correct order is ICBM (1957), Communication Satellite (1962), and WWW (1991), corresponding to the sequence 2-3-1.
