Answer:B
The basic building blocks of the arithmetic unit in a digital computers are __________
A. Subtractors B. Adders C. Multiplexer D. Comparator
Explanation: The basic building blocks of the arithmetic unit in digital computers are adders. Since a parallel adder is constructed with a number of full-adder circuits connected in cascade. By controlling the data inputs to the parallel adder, it is possible to obtain different types of arithmetic operations.
