Solution
The correct option is C London Dispersion
Iodine consists of I2 molecules, and the only attractive forces between the molecules are van der Waals dispersion forces due to the nature of the molecule. This van der Waals force is relatively weak due to the absence of a permanent dipole.
This intermolecular force, although relatively weak allows Iodine to stay solid at RTP. Indeed, there are enough electrons in the I2 molecule to make the temporary dipoles, which create dispersion forces. They are certainly strong enough to hold the iodine together as a solid.
Hence, the correct option is D.
