Option C (The convenience.............downwards) is the correct choice.
Explanation:
Throughout this circumstance, the convenient yield would maintain the very same, although the curve amount or rate will change downwards since it is a transient trading strategy, but perhaps the effects will be negative and then it will proceed to something like a downward shift throughout the convenience curve.
The yielding of convenience might maintain the same because, but perhaps the curve degree may change downwards.
All other decisions are not linked to the circumstance issued. So, the alternative here is the right one.
