At first I was stuck between C & E and then realized that both are wrong

Here's why?
Attorney: I ask you to find Mr. Smith guilty of assaulting Mr. Jackson. Regrettably, there were no eyewitnesses to the crime, but Mr. Smith has a violent character. Ms. Lopez testified earlier that Mr. Smith, shouting loudly, had threatened her. Smith never refuted this testimony.
The attorney’s argument is fallacious because it reasons that
(C) since Smith never disproved the claim that he threatened Lopez, he did in fact threaten her
(E) having a violent character is not necessarily associated with the commission of violent crimes
Conclusion:I ask you to find Mr. Smith guilty of assaulting Mr. Jackson.
Premise1:Mr. Smith has a violent character.
Premise2:Ms. Lopez testified earlier that Mr. Smith, shouting loudly, had threatened her. Smith never refuted this testimony.
Suppose C is correct => S threatened L & accepted testimony => from this we can never say that S assaulted J ..... L & J are different ppl.
Option E has an extra "not"
