Option 2 : Neither II nor III follows
A course of action is something that needs to be done considering the present scenario in mind.
The given sentence is about HSFO which will still flow from refineries around the world even after new rules start up in 2020 reducing its use in the global shipping fleet. And further talks about the fact that 60% of the 33 refineries in a global survey will still produce HSFO in 2020 although the supply will tighten as 70 percent of these refiners plan to reduce their output.
Course of action I talks about the fact that following the imposition of new rules the ships will now use marine fuels which have low sulphur context as compared to HSFO. Thus, this particular course of action is in the direction of the ships adopting new methods thereby, complying with the new rules.
Course of action II states general facts.
From the given context nowhere the incentives of the refiners is discussed thus, it is not relevant to the idea stated. As a result, Course of action III can also be rejected.
From the courses of actions mentioned only I is relevant with the given context thus, the correct answer is option 2.
