Predict the products for the following reaction sequence:

The product $(A)$ of the following reaction is:

The reaction of $1-^{14}C$-chlorobenzene with $NaNH_2/NH_3$ proceeds via a benzyne intermediate. Two benzyne intermediates are formed. Reaction with the amide ion can occur in two different directions for each benzyne, giving three possible products in a $1:2:1$ ratio. Asterisk $(*)$ refers to $^{14}C$. Which of the following represents the major product$(s)$ $(A)$?

Identify the final product of the following reaction sequence:
