本题考查名词的辨析与语境理解。关键点在于理解句子中“work at his ____”的搭配逻辑。需明确每个选项的常见用法及适用场景：

• charge通常指“职责”或“费用”，一般不与“work at”搭配；
• company表示“公司”，符合“工作地点”的语境；
• career指“职业”，但“work at one's career”搭配不自然；
• cash与工作场景无关。

选项分析

A. charge

“Charge”常用于“take charge of（负责）”或“pay the charge（支付费用）”，与“work at”搭配不合逻辑。

B. company

“Company”意为“公司”，“work at his company”表示“在自己的公司工作”，符合句意。

C. career

“Career”指“职业”，但“work at one's career”搭配不常见，通常用“pursue/develop one's career”。

D. cash

“Cash”指“现金”，与“工作地点”无关，排除。
