A)Increased navigation through olfactory cues
B)Disrupted celestial compass orientation errors✓
C)Enhanced anaerobic metabolism in flight
D)Accelerated rate of dehydration ashore
💡 Explanation
Disrupted celestial compass orientation arises because monarch butterflies utilize polarized light patterns in twilight for navigation; therefore, overcast conditions impair their ability to orient effectively, rather than relying more on alternative cues under normal atmospheric conditions.
