a. the discovery of the electron
b. the discovery of gamma rays

d. the invention of microscopes for seeing subatomic particles

I think the correct answer from the choices listed above is option A. The scientific knowledge  that was necessary for Schrödinger’s work would be the discovery of the electron. n order for Schrodinger to develop the quantum model of the atom he needed to be familiar with the works of Neil Bohr and his atomic model.
