The correct answer is

Target site

Target site is correct.

Endocrine glands are ductless glands. They release their hormones directly into the blood, which carries them throughout the body.

A hormone acts only on the particular organ or tissue whose cells carry receptors for it; this organ is called the target site or target organ.

For example, thyroid-stimulating hormone from the pituitary acts on the thyroid gland, and insulin from the pancreas acts on the liver and muscles. Hormonal site, blood site and endocrine site are not the accepted terms.
