B)Mesoscale weather features cannot be predicted.
C)Atmosphere-oceans interactions cannot be resolved.
D)Many more computations are needed.

As grid spacing becomes smaller in computer forecasting models, the number of grid points and therefore the number of computations required increases. This can lead to significant computational challenges and also increase the cost of running the models. The other options, A, B, and C are not necessarily problems arising from smaller grid spacing, but rather limitations/successes of the models in terms of their ability to resolve different scales of weather features or interactions between the atmosphere and oceans.
