Answer 1

The correct option is B holdfast

The body of kelp is attached to a surface by structures called holdfast. The stalk (stem)-like structure is called stipe. The leaf-like structure that photosynthesises is called fronds. Fronds consist of blades and bladders. Blades are the broad leafy part of fronds. At the base of the blades, there are gas filled bladders. It provides buoyancy to lift the blades up towards the water surface.
