The price of gold ______ at $1,300 per ounce over the past week, yet most financial experts agree that it is likely to rise due to a lack of investor confidence in the stock market.
(A ) is stabilizing
(B ) will have stabilized
(C ) will be stabilizing
(D ) has stabilized

這題的正確答案為(D ),雖殘我知道要用”over the past week”來判斷答案,但是這裡的句型結構為什麼可以使用"yet"來當連接詞呢?是否可以幫解析一下這句的結構, 謝謝大家!
