The correct answer is A. Marcian Hoff and Stanley Mazor.
Marcian Hoff and Stanley Mazor were the first to develop a model of the microprocessor chip. They were working at Intel in 1971 when they came up with the idea for a single chip that could perform all the functions of a computer’s central processing unit (CPU). Their invention, the Intel 4004, was the first microprocessor and revolutionized the computer industry.
Victor Poor was also working at Intel at the time, but he was not involved in the development of the microprocessor. Masatoshi Shima was a Japanese engineer who worked for Intel in the early 1970s, but he was not involved in the development of the microprocessor either.
