Which one among the following generation computers used microprocessors in their hardware technology?

The evolution of computers is categorized into five generations based on the underlying hardware technology:

• First Generation (1940-1956): Used vacuum tubes for circuitry.
• Second Generation (1956-1963): Replaced vacuum tubes with transistors.
• Third Generation (1964-1971): Introduced Integrated Circuits (ICs), where transistors were miniaturized on silicon chips.
• Fourth Generation (1971-Present): Utilized microprocessors. This era began with the Intel 4004 chip, which integrated thousands of circuits onto a single silicon chip using Very Large Scale Integration (VLSI) technology.
• Fifth Generation (Present & Future): Based on Artificial Intelligence (AI) and Ultra Large Scale Integration (ULSI).

Since microprocessors are the defining hardware of the fourth generation, Option C is the correct answer.
