The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Auditory Canal**: The auditory canal, also known as the ear canal, is a tube-like structure that leads from the outer ear to the eardrum. It plays a crucial role in hearing by conducting sound waves to the eardrum. 2. **Identifying the Waxy Substance**: The waxy substance that coats the surface of the auditory canal is known as earwax or cerumen. This substance serves to protect the ear canal by trapping dust, debris, and microorganisms. 3. **Recognizing the Glands Involved**: The production of earwax is specifically attributed to ceruminous glands, which are specialized glands located in the skin of the outer ear canal. 4. **Evaluating the Options**: - **Option A**: Glands that produce oily substances for the eye (incorrect). - **Option B**: Parotid gland that produces saliva (incorrect). - **Option C**: Meibomian gland that prevents evaporation of tears (incorrect). - **Option D**: Ceruminous gland that protects and lubricates the auditory canal (correct). 5. **Conclusion**: Based on the evaluation, the correct answer is that the waxy substance coating the surface of the auditory canal is produced by the ceruminous glands. **Final Answer**: The waxy substance which coats the surface of the auditory canal is produced by the ceruminous glands. ---

Surface tension of a liquid is a molecular phenomenon of liquids involving the force of cohesion along the liquid molecules. It is scalar quantity and is numberically equal to the surface energy. Numerically, it is proved that the potential soluble salts and surface active substance. Sparingly soluble salts and surface active substances decrease the surface tension of the liquid. However, the fairly soluble solutes increase the surface tension of the liquid. Surface tension of a liquid is independent of surface area but it depends on the intermolecular forces and the temperature. Which among the following is not the unit of surface tension ?
