I.Steroid hormones are lipid soluble and easily cross the phospholipid bilayer.
II.Steroid hormones usually exert their effects on target cells through membrane receptor proteins.
III.Steroid hormones act on cells close to where they were produced.
IV.Steroid hormones regulate gene transcription by binding to intracellular receptor proteins.
A) I and IV
B) I and II
C) II and III
D) I, II, III, and IV

Option I is correct because steroid hormones are lipid soluble and can easily cross the phospholipid bilayer to enter the target cells. Option II is incorrect because steroid hormones usually exert their effects by binding to intracellular receptor proteins, rather than membrane receptors. Option III is also incorrect because steroid hormones can act on cells that are far away from where they were produced since they travel through the blood. Option IV is correct because steroid hormones regulate gene transcription by binding to intracellular receptor proteins.
