B Correct answer
Explanation

Computer generations are categorized by their primary electronic technology: First generation (1940s-1950s) used vacuum tubes; Second generation (late 1950s-1960s) used transistors; Third generation (1960s-1970s) used integrated circuits (ICs); Fourth generation (1970s-present) uses very large-scale integration (VLSI) and microprocessors. Therefore, transistors characterize the second generation.
