Option B checks that the string country is neither China nor Denmark by using the negation operator (!) to negate the entire expression of checking whether the country is equal to China or Denmark. This means that the expression will be true only if the country is not equal to China and not equal to Denmark, which is logically equivalent to saying that the country is neither China nor Denmark. Option A is incorrect because it uses the logical OR operator (||) instead of the logical AND operator (&&), which means that the expression would be true if either of the conditions is true, which is not what we want. Option C is incorrect because it uses the logical AND operator (&&) instead of the logical OR operator (||), which means that the expression would be false if either of the conditions is false, which is not what we want. Option D is incorrect because it checks if the country is equal to China or Denmark, which is the opposite of what we're trying to check.
