This is a double analogy with two missing pairs. Analyzing YRL→MHZ: Y→M (-12), R→H (-10), L→Z (+14). Now checking option C's first part XQK: Y→X (-1), R→Q (-1), L→K (-1) - all shift by -1. For the second part NIA→MHZ: N→M (-1), I→H (-1), A→Z (-1). This creates a consistent -1 shift pattern throughout.
