Pretty sure your answer is A, however it admittedly could be C. Are there any surrounding sentences, or is this one standalone?
Answer:
C. Haven't
Explanation:
I figured this out by the process of elimination.
"They decided to have a wash <em>have </em>they." This sentence doesn't make sense because this is not the right word to fill in the blank.
"They decided to have a wash, didn't they." Also does not make sense because it is not the right type of past, present, or future tense.
"They decided to have a wash, haven't they." This is the only word that fits this sentence.
From the choices given, the sentence which creates a logical comparison is:
<span>My company’s profits are higher than those of your company.
When making a logical comparison, it should be that you are to indicate the items being compared. In this case, the speaker's company's profits are being compared explicitly to the other specific company's profits. The word "those" refers to the other specific company's profits.</span>
