Answer:
A.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to figure out the correct Lewis dot structure, by realizing chlorine has seven valence electrons, carbon has four of them and nitrogen five, it means that C and Cl form a single a bond and C and N form a triple bond for allowing the three of them to complete the octet; it means Cl remains with three lone pairs, N with one lone pair and C with no lone pairs; therefore, the answer is A.
