(c) No, that's not correct. The question of foreseeability is not a matter for the court to decide according to its own perceptions of what was foreseeable in particular circumstances. This approach would set a very high standard of behavior and the law has not adopted this approach.
To decide whether harm was foreseeable, the courts developed the notion of a reasonable person in the position of the defendant, asking whether such a person would have foreseen the danger in the circumstances.
