i. You cannot instantiate a type variable directly because of type erasure. For example, given a generic class `GenericClass<T>`, you cannot do `T obj = new T();` because at runtime the JVM does not know what `T` is due to type erasure. II and III are incorrect because you can return a type variable and pass a type variable as a method argument in generic code.
