Answer: (B)

Verified step by step guidance

1. Understand the types of bonds: Organic molecules primarily consist of carbon and hydrogen atoms, and the bonds between these atoms are crucial for the structure and function of the molecules.
2. Define covalent bonds: Covalent bonds involve the sharing of electron pairs between atoms. This type of bond is prevalent in organic chemistry because carbon atoms tend to form stable covalent bonds with other carbon atoms and with hydrogen, oxygen, nitrogen, and other elements.
3. Contrast with ionic bonds: Ionic bonds occur when electrons are transferred from one atom to another, creating ions. These are more common in inorganic compounds, such as salts, rather than in organic molecules.
4. Consider hydrogen bonds: Hydrogen bonds are weak interactions that occur between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. While important in biological systems, they are not the primary type of bond in organic molecules.
5. Exclude metallic bonds: Metallic bonds involve a 'sea of electrons' shared among a lattice of metal atoms. These are not relevant to organic molecules, which are typically non-metallic.
