Choose correct if the sentence uses colons correctly or incorrect if it does not. Dear: Sirs, I am very happy with your product.

I think incorrect

You are correct. The use of colon is incorrect in this sentence.

No, that is incorrect. Adding a colon between "than" and "Amy" would make the sentence grammatically incorrect.

No, the sentence is incorrect. The use of a colon after "than" is incorrect. The correct sentence would be: "Gertrude is much taller than Amy, Melissa, and Celia." In this case, the colon is not necessary. The sentence compares Gertrude's height to that of Amy, Melissa, and Celia, without the need for additional punctuation.
