Verified Answer :

I think CHCI3 but I'm not sure though

Answer: \(H_2O\)

Explanation: Benzene or \(C_6H_6\) is a non polar molecule which is bonded by weak london dispersion forces.

Trichloro methane or \(CHCL_3\) is a polar molecule which is bonded by weak dipole dipole interactions.

Oxygen difluoride or  \(OF_2\) is polar molecule but the polarities are in opposite directions and hence cancel out each other. They are bonded by weak london dispersion forces.

Water or  \(H_2O\) is a polar molecule which is bonded by strong hydrogen bonding.

Thus strongest inter molecular forces are present in water due to strong hydrogen bonds.
