Question

target cells
all target cells

have receptors to which hormones bind
are found in the blood
secrete hormones
produce their own hormones

Explanation:

Target cells are defined by having specific receptors. Hormones travel through the blood (but target cells aren't in the blood - blood is the transport medium). Endocrine glands (not target cells) secrete hormones. Target cells don't produce their own hormones in this context - they respond to external (from endocrine glands) hormones. The key characteristic is receptor - hormone binding.

Answer:

have receptors to which hormones bind
