B) it does not expect payments when it is
C) it does not expect payments to be made when they are
D) payments are not to be expected to be paid when

A - 'they' cannot refer to the 'bank'.
B - The first 'it' refers to the 'bank' and the second 'it' refers to 'payments'. Incorrect usage.
C - Correct answer. 'they' refers to 'payments'.
D - Incorrect usage of the passive voice. The original sentence clearly indicates that the bank expects payments. "payments are expected to be paid" - does not answer the question 'to whom?'.
Also, 'payments are expected to be paid' is redundant.
E - same errors with passive voice and redundant usage. The usage of 'will be' is incorrect. This option absurdly implies that payments will be due after payments are expected to be made.
Payments are expected implies that payments are due. (same time frame).
