Clusters of cells that secrete milk D. Lactiferous duct IV. Joins to form a mammary duct Choose the correct answer from the options given below:
Options
- AA-III, B-I, C-IV, D-II
- BA-IV, B-III, C-I, D-II
- CA-III, B-IV, C-I, D-II
- DA-III, B-IV, C-II, D-I
Correct answer
C. A-III, B-IV, C-I, D-II
Step-by-step solution
According to NCERT, the cells of mammary alveoli secrete milk (A-III). The alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct (B-IV). Several mammary ducts join to form a wider mammary ampulla (C-I), which is connected to the lactiferous duct through which milk is sucked out (D-II). Therefore, the correct matching is A-III, B-IV, C-I, D-II. Answer: A-III, B-IV, C-I, D-II
