Answer: Option (d) is the correct answer.
Explanation:
When salt is added to water then the sodium and chlorine ions dissociate.
After the dissociation, both the positive and negative ions that is the sodium and chlorine ions will be surrounded by the water molecules. Thereafter, the positive part of water molecule will be attracted to the negative ions that is the chlorine ions and vice versa.
As sodium ion is a cation so it will hold a positive charge, and chlorine ion is an anion so it will hold a negative charge.
Thus, it can be concluded that when salt is added to water, all of the above will happen except option (d) that is the salt breaks into positive chlorine ions and negative sodium ions.

Max Planck was studying the emission of light by
hot objects. He believed that the hot objects did not emit energy continuously,
as would be expected if it were in the form of waves. Instead he suggested that
the object emits the energy in small, specific amounts called quanta. A quantum
is the minimum quantity of energy that can be lost or gained by an atom. He
proposed the following relationship between a quantum of energy and the
frequency of the radiation: E = hn.
E represents the energy in joules of a quantum of radiation, n<span> is the frequency of the radiation emitted, and
h is a constant known as Planck’s constant. Albert Einstein introduced the idea
that electromagnetic radiation has a dual wave-particle nature. Example: white
light exhibits many wavelike particles, it can also be thought of as a stream
of particles. Each particle of light carries a quantum of energy. He called
these particles photons. A photon is a particle of electromagnetic radiation
having zero rest mass and carrying a quantum of energy.</span>
