{'botulism': [0, 0, 0, 1], 'food poisoning': [0, 0, 0, 1], 'toxin': [0, 0, 0, 2], 'bacterial infections': [0, 0, 0, 1], 'bacterium': [4, 2, 6, 5], 'facial wrinkles': [0, 0, 0, 1], 'anaesthetic agent': [0, 0, 0, 1], 'surgery': [0, 0, 0, 2], 'cancer': [2, 0, 0, 1]}

Option 1: This option is incorrect. Botulism toxin is not used as an anaesthetic agent during surgery. It is actually a paralytic neurotoxin that causes muscle weakness and can lead to respiratory failure.

Option 2: This option is correct. The toxin produced by the bacterium that causes botulism is used in small amounts for cosmetic purposes such as removing facial wrinkles. It is injected into specific muscles to relax them and reduce the appearance of wrinkles.

Option 3: This option is incorrect. Botulism toxin is not used in treating cancer. It is primarily used for cosmetic purposes and not as a treatment for cancer.

Option 4: This option is incorrect. Botulism toxin is not used in preventing bacterial infections. It is actually produced by a bacterium and can cause a severe form of food poisoning when ingested.

In conclusion, the correct option is 2 as botulism toxin is extensively used in removing facial wrinkles.
