Here are the essential concepts you must grasp in order to answer the question correctly.
Polar Covalent Bonds
Polar covalent bonds occur when two atoms share electrons unequally due to differences in their electronegativities. This results in a molecule having a partial positive charge on one end and a partial negative charge on the other, creating a dipole. Understanding the nature of these bonds is crucial for predicting the polarity of molecules based on their structure and the elements involved.

Molecular Formula Analysis
A molecular formula provides information about the number and types of atoms in a molecule, which can help infer the presence of polar covalent bonds. By analyzing the molecular formulas given in the question, one can identify functional groups, such as hydroxyl (-OH) or carboxyl (-COOH), that typically contain polar covalent bonds, thus influencing the overall polarity of the molecule.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In organic chemistry, groups like hydroxyl (-OH) and carboxyl (-COOH) are known to introduce polarity due to their electronegative oxygen atoms. Recognizing these groups in the provided molecular formulas is essential for predicting which molecule has the most polar covalent bonds.
