______ clearly communicate with and actively listen to employees is essential to improve their performance.

选择一项：

A.
Be able to


B.
Being able


C.
Being able to

译文：能清楚的与员工交流并主动聆听他们是提高他们绩效的关键。 解析：此句中is essential to为谓语部分，and连接两个相同的成分clearly communicate with employees 及actively listen to employees，不定式或动名词可以做主语，所以答案是C。 正确答案是：Being able to
