Answer :
Lewis-dot structure : It represent the number of valance electrons present in the element. It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
The given molecule is,
As we know that, carbon has '4' valence electrons, nitrogen has '5' valence electron and chlorine has '7' valence electrons.
Therefore, the total number of valence electrons in = 4 + 5 + 7 = 16
According to Lewis-dot structure, there are 8 number of bonding electrons and 8 number of non-bonding electrons.
In the given molecule, carbon is the central atom because it is more electropositive element than the nitrogen and chlorine. The carbon bonded with nitrogen by the triple bond because nitrogen ability to form triple bond and carbon bonded with chlorine by single bond.
The Lewis-dot structure of is shown below.

Explanation:
Dehydrohalogenation reactions occurs as elimination reactions through the following mechanism:
Step 1: A strong base(usually KOH) removes a slightly acidic hydrogen proton from the alkyl halide.
Step 2: The electrons from the broken hydrogen‐carbon bond are attracted toward the slightly positive carbon (carbocation) atom attached to the chlorine atom. As these electrons approach the second carbon, the halogen atom breaks free.
However, elimination will be slower in the exit of Hydrogen atom at the C2 and C3 because of the steric hindrance by the methyl group.
Elimination of the hydrogen from the methyl group is easier.
Thus, the major product will A
