单项选择题
A hedge fund that takes perfectly offsetting long and short positions is best described as a(n):（）
A. market-neutral fund.
B. long/short fund.
C. event-driven fund.
答案
参考答案：A
解析：
Market-neutral funds take long and short positions but attempt to offset them to hedge against market moves. Long/short funds take both long and short positions but do not try to offset them. Event-driven funds focus on unique market opportunities, not offsetting positions.
