Repayability (Opt-1 / Opt-2)
Notes: Simple nominal annual rates; monthly OD accrual; no tax/fees/penalties modeled.
Each month, interest due is paid first; any remaining amount reduces principal.
Option-1 pays with FD interest only (Bond kept as income). Option-2 uses FD + Bond to repay.
OD principal equals the drawn amount (= OD limit × drawn %).
