I think I should give the reason for my being in Birmingham, since you have been influenced by the argument of “outsiders coming in.” . . . Several months ago our local affiliate here in Birmingham invited us to be on call to engage in a nonviolent direct action program if such were deemed necessary. We readily consented and when the hour came we lived up to our promises. So I am here, along with several members of my staff, because we were invited here. I am here because I have basic organizational ties here. –“Letter from Birmingham Jail,”
Martin Luther King Jr.

According to the letter, why was King in Birmingham?

He had decided on his own to run a protest.
He had been asked to help stage a protest.
He had lived in that city earlier in his life.
He was a member of that community.

He had been asked to help stage a protest.

Explanation:

According to the excerpt from “Letter from Birmingham Jail,” by Martin Luther King Jr, he talks about clearing the air about why he was in Birmingham, and said he was invited by their "local affiliate" in Birmingham who asked that he should be in the city in case a non violent protest was needed.

Therefore, according to the letter, King was in Birmingham because he had been asked to help stage a protest.
