Explanation:

The Intel 80386 (i386), introduced in 1985, was a groundbreaking 32-bit microprocessor that significantly advanced personal computing and workstations. Its power and capabilities allowed personal computers to perform tasks previously reserved for minicomputers, effectively creating a category known as 'super minicomputers' or high-end workstations that could rival traditional minicomputers. The term 'super chip' informally refers to such powerful processors. Option (a) 80586 refers to the Intel Pentium processor, which came later. The other options are not relevant microprocessors for this context. Thus, the 80386 ($ \text{b} $) played a key role in the evolution towards super minicomputers.
