B is correct. Index eligibility works like a checklist: passing one box is not enough if another box fails. The bond meets the euro, corporate, amount, fixed-rate, and BBB ESG facts, but the module states that fixed-rate perpetual bonds are excluded. That single exclusion keeps it out.
A is incorrect. BBB or higher ESG rating is necessary for this index, but it is not sufficient. The fixed-rate perpetual exclusion still applies.
C is incorrect. The index described is a euro corporate sustainable SRI index. It is not an index that requires sovereign or securitized issuers.
