The correct answer is (a) Both assertion and reason are correct and reason is the correct explanation of assertion
Assertion (A): Ionic compounds are solid and hard.
As ionic compounds have a strong ionic bond, the ions are strongly packed together owing to the electrostatic attraction. Hence, the structure formed is solid and hard. This is because it is difficult to break this bond.
Reason (R): They have strong force of attraction between positive and negative ions
Ionic compounds have strong force of attraction between positive and negative ions. This is because the electrons are completely transferred in case of ionic compounds, unlike covalent compounds which share the electrons.
