Step 1: Understand the modal verb usage.
"Can" is the appropriate modal verb for expressing ability or possibility in the present. Here, it indicates the possibility of qualifying in the current year. Step 2: Analyze each option.
- (A) may: Incorrect. "May" expresses permission or possibility but is less certain than "can" in this context.
- (B) might: Incorrect. "Might" is used for less certainty than "may," and is not as strong as "can."
- (C) can: Correct. "Can" expresses the ability to qualify, which is the intended meaning.
- (D) could: Incorrect. "Could" suggests a past ability or a hypothetical situation, which doesn't fit here. Step 3: Conclusion.
The correct sentence is "We can qualify this year."
