To start with, it is necessary to take into account that the prefixes are letters that are situated at the beginning of a word, changing the word's original meaning: Therefore, the prefixes re, dis, un, and al have different meanings. To answer this question it is necessary to understand the meaning of each one:
Re: Again, back.
Dis: Away, separate, not.
Un: Not, revesal of.
Al: Is a suffix whose meaning is related to or like, but it is no a prefix; thus, this option can be discarded.
Therefore, the appropriate answer is A: re because they are going to paint the house again, so they are going to repaint the house. So, the meaning of "Repaint" is the act of paint something again.
I Agree with A (repaint) as well, but for a different reason. There is a fine line between affix and prefix. Affix is a lettter (s) added before the beginning or end to MODIFY its meaning.
Prefix is at the beginning to CHANGE it's meaning.. Define the difference betweem modidy and change... (I can't-- can you? )
In the case of re-paint, i think that repaint can be defined as a prefix or affix. So I pick A..also who else would use those other prefixes.. UnPaint a house.... ? Really? Or Dispaint? Those aren't words.. I still pick A.
It's a redundant sentence because it does not need to say "over and over" and "and repeated it. Also those two phrases are double negatives. It could also be called a run on sentence.
