Which one of the following sentences is capitalized or punctuated incorrectly a The teacher reminded class to remember homework b Remember do your c teache?

All three sentences are incorrectly capitalized and/or punctuated.

* a) The teacher reminded class to remember homework: This should be "The teacher reminded the class to remember their homework." "Class" needs to be "the class," and "homework" needs a possessive pronoun to agree with "class."

* b) Remember do your: This is a sentence fragment and lacks punctuation. It should be something like, "Remember to do your homework."

* c) teache?: This is a misspelling and lacks punctuation. It's likely meant to be "Teacher?" or a similar question.

Therefore, all three options are incorrect.
