Answer
Answer:
No option is correct as written. The original sentence is grammatically correct and does not need parentheses added in the ways presented. If we had to choose the least incorrect in terms of punctuation placement, the original sentence without any added parentheses is the best - but if we must choose from the given options, none of them improve the sentence.
Brief Explanations:
Parentheses are used to add non - essential information. In the original sentence, all information is essential to convey the meaning. Adding parentheses as in the options disrupts the natural flow and does not follow standard punctuation rules for this context.
