The organism which is different from others in the above option is a fungus and causes a disease called "black mold" on certain fruits and vegetables such as grapes, and onions, and is a common contaminant of food.

Complete solution:
Staphylococcus aureus , Vibrio cholerae , and Clostridium tetani , are the bacterial species. These are known as smaller prokaryotic organisms. Aspergillus niger is the species of a fungus. It's a eukaryotic organism that is usually found on damp surfaces and on the surface of stale bread. the expansion is within the sort of mycelial hyphae. They produce black spores.
The Aspergillus niger species is known to be very less likely to cause diseases in humans than other Aspergillus species. In extremely rare instances, humans may become ill, but this is often because of significant lung disease, aspergillosis, which will occur. Aspergillosis is, especially, frequent among horticultural workers who inhale peat dust, which may be rich in Aspergillus spores. The fungus has also been found within the mummies of ancient Egyptian tombs and maybe inhaled once they are disturbed.
Aspergillus niger is cultured for the economic production of many substances. Various strains of A. niger are utilized in the economic preparation of acid and gluconic acid and are assessed as acceptable for daily intake by the planet Health Organization.

So, the correct answer is ‘ Aspergillus niger ’.

Note:
In the year 2007 the strain of ATCC 16404 Aspergillus niger was reclassified as Aspergillus brasiliensis. This has required an update to the U.S. Pharmacopoeia and therefore the European Pharmacopoeia which commonly uses this strain throughout the pharmaceutical industry.
