-- --- is jeremy lin -- he is a famous harvard-educated asian-american nba basketball player
a\ where
b\ what
c\ why
d\ how old
请说明理由好吗?

C.Why 很明显一看就是错的,英语里面没有Why+be+sb?这种句式,除非sb后面还有其他成分,如形容词,动词的ing形式等.
楼主的答句描述的是Jeremy LIN的职业,故问句可以有下了三种表达方法：
1,What's one's job?
2,What does sb do?
3,What is sb?
其中第1,2中表达法较为常见.而楼主的问句是第3种表达法.至此,正确选项浮出水面!
