The correct answer is option A ("Sarcastic").
In this short excerpt from Jonathan Swift's poem "The Lady's Dressing Room", we have a couple of clues that clearly enough indicate a sarcastic tone.
Primarily, what I'm looking at is the choice of words from the author:
The woman is not being addressed as a simple human but rather a female deity or goddess. Her struggles (as large as they may seem to her), are somewhat dismissed or mocked by the poet considering that the lady is surrounded by luxury. The mention of brocades also points towards that tonal direction, given that it's a highly expensive fabric most commonly laced with gold or silver.
Hope this helps!
