Answer :
The correct answer is the following: option C. The most accurate statement about the paragraph presented in the question is that there is no single topic sentence. When writing, a single topic sentence is the one that will state which is the purpose of the paragraph being written. Normally the topic sentence is located at the beginning of each paragraph, although it is not a necessity to do so. In the paragraph shown in the question, there are 9 different sentences, that all correlate to each other and give sense to the paragraph, but there is not a single topic sentence that explains the main purpose of the text or paragraph.
