B解析分析：此處that引出了一個定語從句，在定語從句中是主語，指定語從句所修飾的名詞the ladies，因此這里的that要看成復數(shù)，所以要在are visiting和visit中來決定。根據(jù)句子的意思應該選B項are visiting．(延伸)定語從句的引出詞who，that，which如果是定語從句的主語的話，判斷是單數(shù)還是復數(shù)就要看定語從句所修飾的名詞(即“先行詞”)的數(shù)，如：He lives in the house which(that)is opposite ours．(單數(shù))The shops which (that)are located on Nanjing Road are full of people all the yearround．(復數(shù))
