B Correct answer
Explanation

Saharan desert ants (Cataglyphis) navigate using the polarization patterns of sunlight, which remain stable even when the sun is obscured. They do not rely on landmarks (absent in desert), pheromone trails (ineffective in shifting sands), or dance communication (unique to honeybees).
