In mathematical reasoning, while negating a statement we have to change all \forall statements to \exists statements and then change any one part of the statement. This question can be written as \forall classmates love icecream. So, the negation of the given statement is \exists some classmates who dont love icecream.

And this answer is synonymous to the option There are some classmates who dont love icecream \boxed{\text{There are some classmates who dont love icecream}} which is the correct answer.

Nice problem and solution.
