Looking at the information conveyed by the paragraph, we logically get an idea that E is the opening statement. The next clue is the CA link, where the author talks about gender and class in statement C and then about caste in statement A. The word "Similarly" in the link here. We can reach to the conclusion by using the second clue only.
Hence, option B is the correct answer.
