The correct answer is: A. LISP machines
ART (Automatic Reasoning Tool) is a theorem prover developed by Larry Wos and his students at Argonne National Laboratory in the 1970s. It was one of the first successful implementations of the resolution principle, a general method for proving theorems in first-order logic. ART was originally written in LISP, and it was designed to be used on LISP machines. However, it has since been ported to a variety of other platforms, including personal computers and microcomputers.
LISP machines are a type of computer that is specifically designed for running LISP programs. They were popular in the 1970s and 1980s, but they have since been largely replaced by personal computers and workstations.
Personal computers are a type of computer that is designed for individual use. They are typically smaller and less powerful than mainframe computers, but they are more affordable and easier to use.
Microcomputers are a type of computer that is even smaller and less powerful than personal computers. They are often used for embedded systems, such as those found in cars and appliances.
