Answer:
A. banding
Step-by-step explanation:
Banding is a technique used in floriculture to make decorative decorations. This technique is used when the florist wants the arrangement to have an efficient support that prevents very delicate flowers from loosening, falling or doubling due to their anatomy or some external factor.
The technique consists in tying these flowers together with something resistant and that supports the support, like raffia, for example.
