Which answer shows a correct way to divide the word at the end of a line?

a.
ov-erhead

b.
overhe-ad

c.
over-head

d.
cannot be divided

D. cannot be divided

-A. and B. should be wrong for obvious reasons, (try sounding it out like that lol)
-I thought it might've been C, but this word in English does not need to be divided, so it has to be D.

I might be wrong, because D says "cannot" be divided, cannot being the key word.

My gut still says to choose D.

Hope this helps!
