The correct answer is option 4, which states that all three options - fermentation of sugars, production of vaccines, and cleaning of oil spills - are possible commercial/industrial applications of bacteria.

Let`s dissect each option to better understand it:

Option 1 states that the fermentation of sugars is a possible commercial/industrial application of bacteria. Bacteria are commonly used in industries such as food and beverage production to carry out fermentation and produce products like bread, yogurt, beer, and wine. They convert sugars into various useful metabolites.

Option 2 states that the production of vaccines is a possible commercial/industrial application of bacteria. Certain bacteria, such as Escherichia coli (E. coli), can be used to produce vaccines. These bacteria are modified to express specific antigens that stimulate an immune response and help in the production of vaccines.

Option 3 states that the cleaning of oil spills is a possible commercial/industrial application of bacteria. Certain bacteria, known as oil-eating bacteria or hydrocarbon-degrading bacteria, have the ability to break down oil into less harmful substances. These bacteria can be used in the bioremediation of oil spills.

It is important to note that all three options are independent and can be used in different industries or applications
