Verified Answer
A. पूर्ण आंतरिक परावर्तन / Total internal reflection
B. विवर्तन / Diffraction
C. प्रकीर्णन / Scattering
D. अपवर्तन / Refraction

Explanation:

Optical fibers transmit light over long distances by utilizing the principle of total internal reflection, where light rays are reflected internally within the fiber core due to the difference in refractive indices between the core and cladding.
