<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.
When electron is transferred from less electronegative atom to more electronegative atom.
The atom which is more electronegative gains electron and undergoes reduction reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.
Hence, the correct answer is Option d.

I found this on google
“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”
I hope this helps
