To determine the correct answer, let's analyze the given sentence and the options provided:
"The price ______, but I doubt whether it will remain so."
The sentence suggests that the price has changed, but the speaker is unsure if it will stay the same. We need to identify the past tense form of the verb that indicates a decrease in price.
Let's evaluate each option:
A.
Went down
- This is the simple past tense form of "go down," indicating a decrease in price in the past. However, the sentence suggests uncertainty about the future, so this option is not suitable.
B.
Will go down
- This is the future tense form of "go down," indicating a future decrease in price. However, the sentence already states that the price has changed, so this option is not appropriate.
C.
Has gone down
- This is the present perfect tense form of "go down," indicating that the price has decreased in the past and remains so in the present. This option aligns with the given sentence and the speaker's doubt about the future. Therefore, this is the correct choice.
D.
Was going down
- This is the past continuous tense form of "go down," indicating an ongoing decrease in price in the past. However, the sentence does not provide any information about the duration or continuity of the price decrease. Therefore, this option is not suitable.
Hence, the correct answer is
C. Has gone down.
