Explanation:

- Option 1 says the only difference between S. 299 (culpable homicide) and S. 300 (murder) is the highest probability of death in S. 300. This is partially correct, as S. 300 does require a higher degree of probability, but it’s not the *only* difference.

- Option 2 claims clause (c) of S. 299 and S. 300 both require knowledge of the probability of murder. This statement is misleading, as S. 299 clause (c) refers to knowledge of the likelihood of causing death, whereas S. 300 involves a more certain intention or factual knowledge.

- Option 3 is “Both (a) and (b)," but since both contain inaccuracies or are only partially true, this is not the correct response.

- Option 4 states "None of the above," which is actually correct since neither statement is fully accurate.

Correct Answer: Option 4, None of the above.
