What is true about List and List<?> in Java generics?

List and List are both generic types in Java, however they are not entirely the same. Option A is incorrect because they do have some differences. Option C is incorrect because the wildcard symbol indicates an unspecified type, therefore it cannot be a raw type. Option D is incorrect because both List and List are related as they are both generic types. The correct explanation is that List is known as a raw type since it does not have any generic type arguments specified, while List is a wildcard type which can represent any generic type.
