本题考查知识点为动词“inherit”的正确时态和形式运用。解题思路是根据句子中的时间状语“At the age of 18”来判断句子时态，然后分析每个选项中动词形式是否符合该时态。

• A选项：“At the age of 18”表明事情发生在过去，一般过去时中动词要用过去式。而“inherit”是动词原形，这里应该用“inherited”，所以A选项错误。
• B选项：“inherited”是“inherit”的过去式，与“At the age of 18”所表示的过去时间相匹配，句子时态和动词形式都正确，所以B选项正确。
• C选项：“will”是一般将来时的助动词，后面要接动词原形，而“inheriting”是现在分词形式，所以C选项错误。
• D选项：“inherits”是一般现在时的第三人称单数形式，与“At the age of 18”所表示的过去时间不符，所以D选项错误。
