The elements that both have chemical symbols that are two letters and start with the letter "A" are antimony (Sb) and iron (Fe). Therefore, none of the pairs listed in your responses meet both criteria, as only antimony qualifies with the letter "A."
If I consider pairs strictly based on the criteria mentioned, none of the given pairs fit. If you’re looking specifically for elements starting with "A" that also have two-letter symbols, the correct element is antimony (Sb).
Please check if there were any other pairs or criteria you'd like to clarify!
