    A.where; that

    B.that; when
    C.that; that
    D.where; when

    答案：C
    解析：
    本题考察强调句和定语从句，题目意为“正是在卢浮宫中陈列的那些达·芬奇多年辛苦耕耘的画作，成为世界各地人民为之入迷的胜景。”全句结构为强调句，如果将it is/was...与连接词去掉，句子仍然正确，就为强调句型。这时，就选用that连接词；否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。由此判断此句为强调句。被强调的成分the paintings in Louvre______Da Vinci worked on for years是定语从句，从句作定语修饰paintings，先行词只能用that。
