Directions: In the question below, a statement of Assertion (A) is followed by a statement of Reason (R). Choose the correct option:
Assertion (A): The electrical conductivity of an intrinsic semiconductor increases with rise in temperature.
Reason (R): With increase in temperature, covalent bonds rupture, generating additional free conduction electrons and mobile holes.
Refer to the Case Study 'Case Study: The Chlor-Alkali Electrochemical Process in Chemical Industry' to answer:

Refer to the Case Study 'Case Study: Optical Fibers and Total Internal Reflection in Medical Endoscopy' to answer:
In clinical medicine, why are coherent fiber bundles used in flexible endoscopes rather than non-coherent bundles?
Directions: In the following question, a statement of Assertion (A) is followed by a statement of Reason (R). Choose the correct option:
Assertion (A): Biomagnification of fat-soluble chlorinated pesticides like DDT is highest in top carnivores (fish-eating raptors).
Reason (R): DDT is lipid-soluble, biologically non-degradable, and cannot be metabolized or excreted, accumulating progressively at successive trophic levels.
Refer to the Case Study 'Case Study: Optical Fibers and Total Internal Reflection in Medical Endoscopy' to answer:
