Option B correctly uses the negation operator (!) and grouping parentheses to make sure that city is checked against both "Chicago" and "Dallas", and only returns true if it is not either of them. Option A and D both have the wrong logic as they will always return true. Option C checks if the city is both "Chicago" and "Dallas" simultaneously, which is impossible.
