💡 Detailed Explanation
The correct answer is 「はもとより」 (wa motoyori), which means 'not to mention A, but also B' or 'A is a given, but also B'. It's used when A is an obvious or expected point, and you want to add another, often more impressive, point B. 「はおろか」 (wa oroka) means 'let alone A, not even B', used in negative sentences. 「ばかりに」 (bakari ni) indicates a reason for a negative result. 「はともかく」 (wa tomokaku) means 'setting A aside for now, B is more important'.
