Is this mechanism will be similar to ozonolysis ?
My try :
My Question is will B be the answer ? And what does Me2S do ?

1$\begingroup$ Me2S reduces the ozonide and any remaining ozone. I think the reaction will take place on the more electron rich double bond. The product you have drawn is not one of the options offered among the answers. $\endgroup$– WaylanderNov 28, 2018 at 13:20

$\begingroup$ I highly doubt that the reagent in the first step is O2, and if that's the case, then it's oxidation reaction. But, I'm not sure! $\endgroup$– Rahul VermaNov 28, 2018 at 13:45

$\begingroup$ @rv7 its O3 ,Ozonolysis will happen I think $\endgroup$– Chloritone_360Nov 28, 2018 at 13:47

The first part of your question has been answered in the comment, as for the part about what does $\ce{Me2S}$ do:
The mechanism used here is reductive ozonolysis and $\ce{Me2S}$ acts a reducing reducing agent itself getting oxidised to dimethysulphoxide $\ce{(Me)2SO}$ (DMSO).
As for the mechanism of reductive ozonolysis with $\ce{Me2S}$ here's a helpful link.
