Which navigational outcome occurs when avian iron-cluster receptors fail?

A)Inefficient celestial cue calibration evolves
B)Inability to sense magnetic inclination
C)Disrupted solar-azimuth alignment emerges
D)Elevation-triggered metabolic shift malfunctions

💡 Explanation

Failure of iron-cluster receptors disrupts avian magnetoreception; this biological magnetic compass relies on sensing the Earth's magnetic inclination. Therefore, the bird loses its ability to determine direction using magnetic fields, rather than experiencing issues with sun-based or celestial methods.
