Diagram 7 shows the state of curly hair when dry and wet.
Which of the following statement explains the situation?
Covalent bond in protein molecules of hair is broken with the presence of water molecules.
Protein molecules in hair forms hydrogen bond with water molecules when hair is wet.
Protein molecules in hair absorbs water when wet, causing the molecular size to increase.
Electrons in the protein molecules are delocalised to form sea of electrons causing wet hair to appear straight when wet.
