In a nested subquery, the innermost query is executed first to fetch the required data, which is then passed on to the outer queries in the hierarchy. The outer queries utilize the data from the inner queries to perform additional filtering or calculations, but the innermost query is executed first to provide the necessary foundation for the rest of the logic. Therefore, option A is the correct answer.
