Right option is (d) High tolerance to butanol

To explain I would say: S. cerevisiae has high toluene level and produces butanol through fermentation of carbohydrates while the other options like high growth rate, overcoming toxicity and changing of the cell wall composition is related to E. Coli, Pseudomonas putida and bacillus subtilis respectively and not related to s. cerevisiae.
