His refusal to answer questions

His arrival in town in a canoe.

Excerpt:

Several people in the crowd interrupted and begged him not to talk that way to an old man and a preacher.

“Preacher be hanged, he’s a fraud and a liar. He was up at the Pint that mornin’. I live up there, don’t I? Well, I was up there, and he was up there. I see him there. He come in a canoe, along with Tim Collins and a boy.”“Preacher, my butt—he’s a fraud and a liar. He was up at the point in the morning. I live up there, don’t I? Well, I was up there, and so was he. I saw him up there. He came in a canoe along with Tim Collins and a boy.”

I believe that the first thing that cast doubt on the authenticity of the king being Peter Wilk's English brother is his illiteracy and inability to write. He struggles with the word funeral obsequies, instead he says funeral orgies.

I believe that the first thing that cast doubt on the authenticity of this is C) his illiteracy and inability to write.
He misuses the word funeral orgy, instead of funeral obsequies, which confirms the doctor's suspicions of this fraud.

I would say that the first thing that cast doubt on the authenticity of the King being Peter Wilk's English brother is his illiteracy and inability to write. He uses the word funeral orgies instead of funeral obsequies. 

I would think it would be the second one, his arrival in town in a canoe. IM not 100% positive but im sure thats the answer.

Their faulty English accent was the first sign of doubt about the two conmen.  Doctor Robinson pointed out that their English accent was terrible.  When the two conmen decided to suddenly sell all of Peter Wilkes’ possession right after his funeral.  Wilkes’ daughters as well the whole tow were against this and it aroused more suspicion but the two conmen proceed to do so prompting Huck to tell one of the girls the truth about two men and the money.
