Toefl grammar test

Hi everyone,------------------------------------
That was Shirley S. Chisholm who was the first Black woman to run for the office of President of the United States in 1972.

Why A is correct? I thought A should be replaced with "it" or "she". Please, explain when we can use it for referent.

I'm sorry, but I don't see any A in that sentence...

The sentence seems good to me.

**Neither a teacher nor a native speaker.**

Cheers!

In this section of the test of Toefl, each sentence has four underlined words or phrases. The four underlined parts of the sentence are marked A, B, C, and D. We have to identify the one underlined word or phrase that must be changed in order for the sentence to be correct. Thanks again.
