Explanation:

The correct option is (b) HITAC S-300. The HITAC S-300, developed by Hitachi in Japan, is widely recognized as Asia's first supercomputer, introduced in the early 1980s. It was a significant technological achievement for the region. Option (a) CRAY-3 was an American supercomputer developed by Cray Research, not an Asian one. Option (c) PARAM refers to a series of supercomputers developed by India (CDAC), such as PARAM 8000, which were India's first indigenous supercomputers but not Asia's first overall. Option (d) EKA was an Indian supercomputer developed by Computational Research Laboratories in 2007, making it a much more recent development than the HITAC S-300.
