Amir was very insecure and filled with hatred , he couldn't accept him as an equal.
Answer: but, however, in spite of, on the other hand, nevertheless, nonetheless, in contrast, on the contrary, still, yet AND first, second, third, next, then, finally
Explanation: These are some good transition words to put with your sentences. If your writing about a topic with 3 points, you can start the paragraph off with "first, second", ect. If your wanting to transition into something different, then use some words such as "but, however, in contrary", ect. It all depends on what your writing about and what type of essay your writing so make sure you use them appropriately.
In my opinion, you always wait till the end and do it when you are done with everything.
I think A seems most appropriate, but not %100 sure.
hope this helps u
