B Correct answer
Explanation

In compound leaves, the term 'pinna' (plural: pinnae) refers to the individual leaflets that make up the compound leaf. The main leaf is the entire compound structure, the rachis is the central axis, and feather is the literal meaning of the Latin word pinna, not the anatomical structure.
