AIIMS 2019 Chemistry Isomerism MCQ Question

Option B is correct because it represents the structure that accurately depicts the functional groups and bonding patterns present in the compound, which is crucial for understanding its reactivity and properties. The other options fail to represent key features such as the correct arrangement of atoms or the presence of specific functional groups, leading to misinterpretations of the compound's chemical behavior. Understanding these structural nuances is essential for predicting how the molecule will interact in biological systems, such as its solubility in H₂O or its ability to participate in biochemical reactions.
