Why Is the H-F Bond So Much Stronger Than the H-I

Why is the H-F bond so much stronger than the H-I bond?

A) H-F is a stronger bond because hydrogen and fluorine are more similar in nature than hydrogen and iodine. Both hydrogen and fluorine are diatomic and gases at room temperature.
B) H-F is stronger bond because iodine forms a solid at room temperature and fluorine forms a gas. Also, iodine tends to sublime at room temperature.
C) H-F is stronger because the fluorine atom is smaller and closer to the hydrogen atom causing greater attraction.
D) Actually, H-I is stronger because the electronegativity of the iodine atom is smaller that that of the fluorine atom.
