What does molecule means?
A molecule is a gathering of at least two particles kept intact by alluring powers known as compound bonds; contingent upon setting, the term might possibly incorporate particles which fulfill this basis.
A molecule might be homonuclear, or at least, it comprises of iotas of one compound component, for example two iotas in the oxygen molecule (O2); or it could be heteronuclear, a synthetic compound made out of more than one component, for example water (two hydrogen iotas and one oxygen molecule; H2O). Iotas and complexes associated by non-covalent for example, hydrogen bonds or ionic bonds, are commonly not thought about single molecules.
Molecules as parts of issue are normal. They likewise make up the vast majority of the seas and climate. Most natural substances are molecules. The substances of life are molecules, for example proteins, the amino acids of which they are created, the nucleic acids (DNA and RNA), sugars, carbs, fats, and nutrients. The supplement minerals are for the most part ionic mixtures, in this manner they are not molecules, for example iron sulfate.
Therefore Option(d) is correct.
