The correct answer to the question: Which of these extracellular signal molecules could diffuse through a plasma membrane and bind to an intracellular receptor? Would be: Estrogen.

Explanation:

Estrogens are steroidal hormones produced mainly by the ovaries, and later by other tissues during pregnancies, in females. The reason why these hormones can simply diffuse through a plasma membrane and bind intracellularly to receptors near the nucleus and other organelles, instead of on the receptors at the plasma membrane's surface comes from the chemical composition of this particular female reproductive hormone. Estrogen is basically a steorid hormone, and its chemical composition as such contains cholesterol, which makes it a lipid-soluble hormone.
