The correct Answer is:
To determine which option is correctly matched, we will analyze each option one by one. ### Step-by-Step Solution: 1. **Option (a): Oxyntic cells - a secretion with pH between 2.0-3.0** - Oxyntic cells, also known as parietal cells, are found in the gastric glands of the stomach. They secrete hydrochloric acid (HCl), which indeed has a pH range of about 2.0 to 3.0. Therefore, this option is **correctly matched**. 2. **Option (b): Alpha cells of islets of Langerhans - secretion that decreases blood sugar level** - Alpha cells are part of the islets of Langerhans in the pancreas, but they secrete glucagon, which actually increases blood sugar levels. The cells that decrease blood sugar levels are the beta cells, which secrete insulin. Hence, this option is **incorrectly matched**. 3. **Option (c): Kupffer cells - digestive enzyme that hydrolyzes nucleic acid** - Kupffer cells are specialized macrophages located in the liver. Their primary function is to phagocytize pathogens and dead cells, not to produce digestive enzymes. They do not hydrolyze nucleic acids. Therefore, this option is **incorrectly matched**. 4. **Option (d): Sebaceous glands - secretion that evaporates for glands** - Sebaceous glands produce sebum, an oily substance that helps to lubricate the skin and hair. This secretion does not evaporate; instead, it forms a protective layer on the skin. Thus, this option is also **incorrectly matched**. ### Conclusion: The only correctly matched option is **(a) Oxyntic cells - a secretion with pH between 2.0-3.0**. ---
