I choose answer “C” (not enough information given).
Done them all (CFA, FRM, CAIA) and in my opinion they are worth doing when your company pays for it and you like studying. CAIA is the most interesting, the easiest, and the most expensive. FRM was quite hard (level II is harder than CFA I) and less interesting, but a lot cheaper. CFA is the best known and relatively cheap, but it takes 2,5 years and is hard.
