based only on the given fermentation test results, we could interpret that the bacteria gives a positive test for fermentation test.
the middle tube clearly shows A/G result, i.e, acid production as well as gas production. the last also seems to be A/G.
By comparing the results with the table, I think the bacteria could be Enterobacter aerogenes or Escherichia coli, since both the bacteria show same fermentation results and that matches with the given image.
however, in the given options, only E. coli is there. so I think it should be E. coli.
