Yes...it's Dow's process then :)

@Pritish : #2 Yes it is Benzyne Mechanism

#4 Dow's Process is something different i guess ??

@Govind Yes ur ans is correct

But can u show the mechanism ??

I mean the stability part

Y is m - cabanion more stable ??

Uttara isi ko Dow's process kehte hain it follows benzyne mechanism. Only difference here is that there is a methyl group also.
Stability of m-carbanion is to do with inductive effect. Ortho position being closer feels the full brunt of methyl group's inductive effect...+R effects are not considered in benzyne mechanism.
