and句型中前后省略如何判断？

我看到这么一题，实意动词什么意思啊？
例题.

In 1973 mortgagepayments represented twenty-one percent of an average thirty-year-old male’s income; and forty-four percent in 1984.

A income; and forty-four percent in 1984

B income;in 1984 the figure was forty-four percent

C income，and in 1984 forty-four percent

D income，forty-four percent in 1984 was the figure

E income that rose to forty-four percent in 1984

A 分号连接两个完整的句子，故A错

B正确

C and前的并列分句使用实意动词represent,在第二个分句中省略实意动词，不符合并列句的省略规则

D 逗号连接两个完整句子。错误

E that就近修饰income,income rose to forty-four percent不合理
