Explanation

Option B is correct because Fitch Ratings specifically highlighted the significant external debt repayment burden for FY2025. Option A is incorrect because the question asks about a specific financial challenge mentioned by Fitch, not just any decline in FDI. Option C is incorrect because remittances are generally viewed as a source of foreign exchange, not the primary stated challenge regarding repayments. Option D is incorrect because while deficits are an issue, the specific figure cited by Fitch for the major challenge was debt repayment.
