The best description of how the author presents the information in the excerpt you provided is D: in a whimsical way, involving satire and hyperbole.
Chesterton employs a humorous, playful tone and exaggerates the difficulties and responsibilities related to writing serious literature versus frivolous content. His use of satire is evident in his critique of the seriousness with which some people approach literature and the ease with which one can write trivial pieces compared to the effort required for more serious writing. This whimsical style underscores his lighthearted yet critical perspective on literary culture.
