How do hormones travel to their target cells?
a) they diffuse through intersitial fluid
b) they travel through the bloodstream
c) they are transported directly from one cell to another
d) they only act locally on the cells near where they are produced

B) They Travel through the bloodstream

Explanation:

they circulate freely through the bloodstream, but sometime they could use a protein hormone transporter that is the case of the steroidal hormones. When they use a protein hormone transporter is because the hormone could be hydrophobic, reduce molecule losses or make a hormone reserve in the bloodstream
