The PEACK (active low) when activated, the pin that goes into deactivation is

(a) PEREQ

(b) ERROR#

(c) RESET

(d) CMD0 and CMD1

This question was posed to me in an online interview.

This is a very interesting question from 80287 Math Coprocessor -2 topic in portion 80286-80287-A Microprocessor with Memory Management and Protection of Microprocessor

Correct answer is (a) PEREQ

To elaborate: When the data transfer is over, the CPU activates PEACK (active low)# pin, which results in deactivating the PEREQ pin by 80287.
