a) The number of sodium ions is equal to the number of formula units of salt.
Explanation:
In the given reaction of NaCl
i.e. Na+ + Cl- →NaCl.
Number of sodium ions = Number of chloride ions = number of formula units of salt. Hence, the only correct option among all is, the number of sodium ions is equal to the number of formula units of salt. Rest all options are incorrect.
