Show answer & explanation
Correct answer: C
The instruction JNBE stands for Jump if Not Below or Equal in 8086 assembly. The condition for the complementary instruction JBE (Below or Equal) is triggered when CF = 1 OR ZF = 1. Consequently, the inverse condition for JNBE requires both flags to be clear simultaneously, meaning CF = 0 AND ZF = 0.
