Not all puts and calls have to do with options (e.g. there are put warrants, call warrants, puttable bonds, callable bonds, etc.), but it looks like all the existing questions in the "puts" and "calls" tags are about options.
Move all the "puts" and "calls" questions into "put-options" and "call-options".
Reasoning: All "puts" and "calls" questions are currently about options. It makes little sense to have multiple tags that deal with exactly the same topic. I don't think tag synonyms are appropriate, because there are legitimate uses of "puts" and "calls" outside options.
Delete the "puts" and "calls" tags.
Reasoning: The generic "puts" and "calls" tags should be deleted because they are too tempting to use for options. For uses outside options, there is currently no demand so deletion is safe. To avoid the use of "puts" and "calls" in the future, instrument-specific tags could be created when the need arises (e.g. "put-warrants", "callable-bonds", etc.).
