Which of these measure-word usages is WRONG?
全球翻车率（内测预估）
A一头蒜
yì tóu suàn · one bulb of garlic
B一头牛
yì tóu niú · one cow
C一头汗
yì tóu hàn · a head covered in sweat
✓一头鱼
yì tóu yú · one fish
蒜有头，牛有头，汗都能满头——偏偏鱼不行，鱼是“条”。量词的世界，鱼哭晕在案板上。
一头 works for garlic bulbs (一头蒜!), cattle, and even a head of sweat (一头汗) — but never fish. Fish take 条.
