1. hydrogen bonds in water molecules are formed between:

nuclei of adjacent molecules.
two hydrogen atoms of the same molecule.
ions in solution between the molecules.
hydrogen and oxygen atoms of adjacent molecules.
two oxygen atoms of the same molecule.

Explanation:

Hydrogen bonds in water are intermolecular forces. Water has a bent shape with oxygen (electronegative) and hydrogen. The hydrogen (from one water molecule) is attracted to the oxygen (of an adjacent water molecule) due to partial charges. Nuclei are not involved in hydrogen - bond formation. Bonds within the same molecule (like between two H or two O of the same \(H_2O\)) are covalent, not hydrogen bonds. Ions in solution are not relevant to the basic hydrogen - bond formation between water molecules.

Answer:

hydrogen and oxygen atoms of adjacent molecules.
