The correct option is B Scape
Scape is the stalk of the stem that attaches the flower to its inflorescence. Onion plants produce a leafless flowering stem which exhibits scape. These have 2-4 leaves that are circular and hollow in cross-section, easily flattened when young. Whereas Torus is the thickened part of the stem from which flower grows. The older name of the torus is thalamus. Pedicel is short flower stalk that attaches the flower to inflorescence.
Thus, the correct answer is option B.
