Best answer
The correct answer is (b) 8087

To explain I would say: 8087 is a coprocessor which can perform all the mathematical functions including addition, subtraction, multiplication, division, exponential, logarithmic, trigonometric etc. 8086, 8080 and 8088 are microprocessors which require the help of a coprocessor for floating point arithmetic.
