The correct answer is A) Also, the word ketchup has an interesting story.
<em>The most effective way to invert sentence 6 in order to vary sentence patterns is: "Also, the word ketchup has an interesting story."</em>
In grammar and editing, you have to vary the sentence pattern in order to not sound too monotonous. Reading the text or paragraphs should sound natural and with rhythm. So in the case of this passage, when you add the word "also" at the beginning of the sentence, it changes the style of writing and when the reader sees "also", they know that more or better information is coming.
