Final answer:
Basophils, which are a type of white blood cell staining dark blue to purple, are associated with immune responses; however, ACTH, TSH, FSH, and LH are hormones produced by the pituitary gland, not by basophils or any blood cells.
Step-by-step explanation:
The correct option : c
Basophils are the type of blood cells that stain blue/purple and are associated with producing hormones such as ACTH, TSH, FSH, and LH. Basophils have large granules that stain dark blue to purple and a two-lobed nucleus. Basophils are a type of white blood cell known as granulocytes. They are characterized by their large granules that stain dark blue to purple during laboratory testing. Basophils play roles in immune responses, particularly those related to allergies and hypersensitivity, as they can release histamine and other inflammatory mediators.
However, the hormones ACTH (adrenocorticotropic hormone), TSH (thyroid-stimulating hormone), FSH (follicle-stimulating hormone), and LH (luteinizing hormone) are actually secreted by the pituitary gland, not by basophils or any other blood cells. The pituitary gland is an endocrine gland, which is part of a different system than the hematopoietic (blood-forming) system that creates basophils.
