The aspect of Rutherford's model that was corrected by Bohr's model is:

A. Electron move freely in curved paths around the nucleus.

Rutherford's model suggested that electrons orbit the nucleus in a way similar to planets orbiting the sun, which implied that they could spiral into the nucleus under electromagnetic force due to the attraction between the positively charged nucleus and the negatively charged electrons. Bohr's model introduced quantized energy levels for electrons, explaining that they occupy specific orbits (energy levels) and do not continuously radiate energy, thereby resolving the instability predicted by Rutherford's model.
