Answer: e. YqhD gene

Explanation:

The researchers showed that most of the isobutanol produced in E.coli strains is due to the action of the alcohol dehydrogenase YqhD. Remember that E. coli has several genes encoding for alcohol dehydrogenases.

They deleted the yqhD gene and found a 80% reduction in isobutanol production.
