Answer 1

The correct option is B

(i) Lactiferous duct (ii) Lobule (iii) Lobe (iv) Acini

In the given cross section of breast, the parts labelled are lactiferous duct, lobe, lobule and acini respectively. The breast is made up of radially arranged lobes which are further divided into lobules. Each lobule contains many clusters of acini which are lined with milk producing cuboidal epithelium. These cells are responsible for the production of milk.
