Why is it A?

Hi Audrey, thanks for the question. This question uses two of the facts to produce the correct answer choice. Since this mole uses its tentacle to detect electric fields produced by animals, and this is how it catches worms and insects, then it is most strongly supported that worms and insects produce electric fields. I hope this helps. Please let me know if you have any other questions or would like me to elaborate further.

Why is the answer not E? Thanks
