The correct answer is option 4: Neutrino. In the recent past, there were claims that a fundamental particle was observed to travel at a speed greater than that of light in a vacuum at a European Laboratory in Geneva. This particle is the neutrino.

To understand this better, let`s look at the other options:

- Option 1: Electron. Electrons are negatively charged particles that are abundant in atoms. While they play a crucial role in electricity and chemical bonding, they have not been observed to travel faster than the speed of light.

- Option 2: Positron. Positrons are the antiparticles of electrons and have a positive charge. Like electrons, they have not been observed to exceed the speed of light.

- Option 3: Neutron. Neutrons are neutral particles found in the nucleus of an atom. They do not have an electric charge and are not associated with the recent claims about particles traveling faster than light.

In conclusion, the correct answer is option 4: Neutrino, which is the particle that has been claimed to travel faster than the speed of light in vacuum.
