Basophils are notably involved in attacking which of the following?

Basophils play a crucial role in the body’s immune response, particularly in allergic reactions and the defense against parasitic infections. These white blood cells are a type of granulocyte and contain granules filled with histamine, a compound that is released during allergic responses. When basophils are activated, they release histamine and other chemicals that contribute to inflammation and attract other immune cells to the site of the allergen.

In the context of allergies, basophils help mediate symptoms such as itching, swelling, and redness, which are common manifestations of allergic reactions. They also play a role in the development of hypersensitivity to allergens through their interactions with other immune cells, particularly T-helper cells, enhancing the overall allergic response.

The other options, while involving different types of immune responses, are not primarily associated with basophils. The distinction lies in basophils' specific function and the types of immune challenges they address, particularly their significance in allergy-related processes.
