Answer:
The answer is option B
Step-by-step explanation:
The yield from Bank E is the lowest among all banks (6.00 percent), and it will get a $100 million offer made by it first. Next, Bank A will obtain an allocation (out of $450 million) in the amount of $150 million bid made by Bank A as its yield is very higher than Bank E but lower than other banks (B , C and D).
Bank C will ultimately get a $150 million bid as its yield is higher than Bank E and Bank A but lower than Bank B and Bank D. Eventually, the remaining $50 million (450-100-150 million-150 million) bid goes to Bank B with higher yields than all banks (except Bank D).
