For the answer to make sense to you, first you need to know that ten thousand (10,000) is called 万 wàn in Chinese.
无 wú means no or without, while 失 shī means to lose something.
The riddle (9999) can be thought of as 10,000 minus 1. In other words, 万 without 1 (i.e. losing 1). Which is why 万无一失 is the best-fitting answer. The other MCQ option (久久不忘) was simply chosen because 久 jiǔ sounds exactly like 9 jiǔ.
The phrase itself means "foolproof" or "without a chance of error or risk". It can be used to express confidence or certainty in a plan or action.
