Answer
The answer is **c. Dalton's postulate**.Here's why:* **Bohr's model** was a significant improvement over earlier models, specifically addressing the behavior of electrons within atoms and the resulting spectral lines. It incorporated concepts like quantized energy levels and the relationship between electron transitions and emitted/absorbed photons.* **Dalton's postulates**, while important in the history of atomic theory, predate Bohr's model and don't encompass the nuances of electron behavior and spectral lines. Dalton's theory focused on the indivisibility of atoms, their constant mass, and their combination in whole-number ratios to form compounds. Bohr's model built upon and refined Dalton's work by introducing the concept of subatomic particles and their arrangement.
