The correct option is D Soddy and Fazan
Group displacement law was given by Soddy and Fazan.
According to this law,
1. Only one type of particle is emitted at a time.
2. When an alpha particle is emitted, the newly formed element will have an atomic number less by two units. The mass number reduces by four units while the group position is shifted two places towards the left.
3. When a beta particle is emitted the newly formed element will have an atomic number increased by one unit, while the mass number remains the same and the group position moves one position toward the right.
