Rubber is a nonconducting material that is why it cannot easily conduct heat and electricity. Which is the best explanation for this situation?. A. it has excess electrons which are loosely bounded with its nuclei so it can free to move B. it has a deficiency in electrons which are tightly bounded with their nuclei so it can not move freely C. it has few electrons D. it has no electrons
