Answer:
B. climatic conditions
Step-by-step explanation:
After reading this excerpt from Katherine Mansfield's "The Garden Party" it is clear that Mansfield uses climatic conditions to describe the setting.
She clearly says “And after all the weather was ideal. They could not have had a more perfect day for a garden-party if they had ordered it. Windless, warm, the sky without a cloud. Only the blue was veiled with a haze of light gold, as it is sometimes in early summer.” She explicitly refers to the cloudless sky and the ideal conditions for a party outdoors since there was no wind and it was warm.
