I was asked this question, and have no idea of the answer as I don't understand the question itself. The answers included: a) Income investment return b) Capital investment return c) Inflation return d) Both a) & b) e) tax credits f) None of the above. - Again, I tried to do my homework to help me understand this question and find the answer, though I think theres a mistake in the way the question was written. If you know anything on returns from trading bonds, maybe you would have an idea of what this question is trying to ask and its correct answer above? Note: My answer would have been d) Both a) & b), if the question was simply: What types of returns can you receive from trading bonds?
