Claim: Make a recommendation for how to make the road safer. Your recommendation could include any combination of changes to the speed limit installation of a guardrail, and setting a vehicle mass limit for the road.

Evidence:
For your recommendation, present data that provide evidence for the recommendation.

Reasoning:
For your recommendation, explain how your evidence supports your recommendation.

your picture is not part of the scientific method.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

it is b that is the answer.
