If genetically engineered bees could express a receptor for TNT in their olfactory neurons, how could the transgenic bees be useful for detecting explosives?  

A.  Watch for death of the bee when the neuron absorbs TNT. B.  Use MRI to monitor the brain activity of the bee. C.  Train bees to respond in a predictable way when the TNT neuron is activated by conditioning them to expect an associated food reward. D.  Grind up the bee's antennae for use in a TNT ELISA assay.
