Explanation
90% electrostatic and 10% covalent accurately defines or describes the concept asked in this question. Within Chemical Bonding, precise definitions and terminology are essential for clear scientific communication. The other options (100% covalent, 50% covalent and 50% electrostatic, and 100% electrostatic) either describe related but distinct concepts, use incorrect terminology, or confuse similar-sounding terms that have different scientific meanings. A thorough understanding of exact definitions helps distinguish between closely related biological concepts and is crucial for competitive examinations.
