Respuesta :
The right answer would be option D. when school funds are sufficient again, we will reinstate the arts programs.
What makes this option the most fitting one is the use of refined register and a standard compound sentence organization. Language register is refined through the use of compound nouns i.e. school funds , and a prefixed verb i.e. reinstate. At the same time, the sentence is a compounded one, clearly organized by having a dependent clause be followed by an independent one,.
