Option 1 - acetic acid: Acetic acid is the main component of vinegar, and it is not found in bee venom.

Option 2 - sulphuric acid: Sulphuric acid is a strong mineral acid that is not found in bee venom.

Option 3 - citric acid: Citric acid is found in citrus fruits and is commonly used as a food additive. It is not present in bee venom.

In conclusion, methanoic acid is the correct answer as it is the acid that is injected by a bee sting, causing pain and irritation.
