(b) CY=1,AC=1

(d) no relation with AC and CY

This question was posed to me by my college director while I was bunking the class.

This intriguing question originated from Arithmetic and Logic Instructions in section 8051 Microcontroller of Microcontroller

Answer 1

The correct option is (c) CY=0,AC=0

The explanation: When we divide two numbers then AC and CY become zero.
