View correct answer and explanation

Correct answer: A

Correct Option: A (it is dipolar in nature) Explanation: Water molecules have a polar (dipolar) charge distribution that attracts ions and other polar molecules, making water a powerful solvent. Option-wise Analysis: A. Correct-water’s dipole and hydrogen bonding promote dissolution of many solutes. B. Incorrect-High thermal conductivity does not explain ionic/polar solubility. C. Incorrect-High specific heat buffers temperature but is not the main solvent mechanism. D. Incorrect-Being hydrogen oxide states chemical composition, not the polarity mechanism.
