Chemistry, WILL MARK BRAINLIEST NEED AS SOON AS POSSIBLE

answer; /// i do believe that the correct answer is (c)nuclear bond

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

1 is the answer to this problem
