Based on the provided @AuthorInfo annotation definition, the 'date' attribute is mandatory and has to be provided. The 'author' and 'comments' attributes are optional due to their default values. Option D correctly specifies the 'date' attribute. Option E not only provides the 'date' attribute but also includes optional attributes 'author' and 'comments' in the correct format. The other options either miss the mandatory date attribute or incorrectly format the annotation.
