Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Chloride ions can be oxidized to chlorine gas.
${M n O}_{2} + 4 {C l}^{-} \to M n C l_{2} + 2 H_{2} O + {C l}_{2} ↑$
We know that chlorine is a halogen.
All the halogens have 7 electrons in their valence shell.
They need 1 electron to complete their octet and be stable.
Hence, 2 chlorine atoms share 1 electron each with one another and form a diatomic chlorine molecule by forming covalent bond.
