B. Favorable heritable traits increase in frequency across generations.
Explanation: Natural selection acts on heritable variation. Individuals with traits that improve survival or reproductive success leave more offspring, so those advantageous alleles become more common over time, producing adaptation. Options A, C, and D are incorrect for the reasons stated (no conscious choice, traits aren’t produced instantly by the environment, and populations don’t adapt by simply stopping reproduction).
