D would be the right answer!
No, the sentence given:
_________________________
"<span>i came home late; therefore, i didnt see aunt matildia" — is NOT punctuated correctly.
____________________________________________
The word: "didnt" should be replaced with: "didn't" (note the added "apostrophe")—or rewritten as two word: "did not".
Furthermore, there should be a "period" at the end of the sentence.
___________________________
As far as other grammar errors are concerned, the second instance of the use of the personal pronoun, "I"—is incorrectly written in the lower case: "i"—and should be replaced with the capital letter, "I". Furthermore, "</span>aunt matildia" should be rewritten with a capital letter "A" replacing the word: "aunt" [the word: "aunt" should be changed to "Aunt"], and the name: "matildia" should be rewritten with a capital "M" replacing the name: "matildia" [the name "matildia" should be replaced with "Matildia"]. Also, if "Aunt Matildia" is, in fact, really spelled that way, than the spelling of the name should be retained. On the other hand, if the aunt's name is actually spelled: "Mathilda"—or some variant, then the proper spelling should be used—and the first letter should be capitalized.

--Edit--- your question should read as follows: "Is this sentence punctuated correctly?"
Answer:
He says that he is cunning and that he acts wisely, as well as saying that he knows what he is doing. These are characteristics that he claims that crazy people don't have.
Explanation:
The narrator of "The Tell Tale Heart" exhibits strange, uncomfortable and crazy behavior in his murder plans and even the reasons for the murder make the reader see him as crazy. However, this is not what the narrator wants. He wants everything he says to be taken seriously by the reader and for this reason, he says that he has characteristics that crazy people cannot be astute, act wisely and know what he is doing.
This does not justify the narrator's sanity.
