A
Asthma
B
Anaphylaxis
C
Lymphyadenitis
D
None of the above
Explanation: 

Detailed explanation-1: -Anaphylaxis is when you get severe allergic reactions. Examples include reactions to certain foods or particular insect stings. Going into anaphylactic shock can be life-threatening.

Detailed explanation-2: -A severe allergic reaction (anaphylaxis) to bee stings is potentially life-threatening and requires emergency treatment. A small percentage of people who are stung by a bee or other insect quickly develop anaphylaxis.

Detailed explanation-3: -Only about 1 percent of bee stings result in anaphylactic shock, with it more likely to happen in people over the age of 25. This is because the more an allergic person is stung, the more severe the reactions get. Children, who likely have only been stung one or two times, will rarely experience such extreme reactions.

Detailed explanation-4: -Causes of the allergic reaction Bee venom contains proteins that affect the skin cells and immune system, resulting in pain and swelling at the site of the sting, even if a person is not allergic to the venom. In those who are allergic to bee stings, the venom triggers a more severe immune system reaction.

Detailed explanation-5: -All symptoms of an “ordinary” sting are at the sting site itself. Expected effects are pain, swelling, redness, and itching. All effects are at that specific spot. Even if the area is still red, swollen, itchy, and painful the next day – it’s an expected reaction, not an allergic reaction.
