B Correct answer
Explanation

The Intel 80486 (1989) was the first Intel microprocessor to include on-board (L1) cache memory - it had 8 KB of unified cache. The 80386 had no on-board cache, while Pentium and Pentium Pro came later and expanded on this concept. The 486's integrated cache significantly improved performance by reducing memory access times.
