I expect animal welfare in D to be higher than in C, almost by definition. In D, the purpose is to have as many animals as happy as possible, without killing them. Whereas in C, the prime objective remains killing and eating the animals. The farmers do not intend to maximize the welfare of the farmed animals. The population in D may be lower than in C, but the population size in D is chosen to maximize animal welfare, whereas the population size in C is chosen to maximize farmers profits. If population size in C is larger than in D, the welfare of the animals in C is suboptimal.
With choosing option C for others, I actually meant not trying to reject option C for others, e.g. not campaigning against option C, not spending money on trying to switch people to option A instead of option C. I agree that the most cost-effective invertebrate welfare interventions are more effective than interventions to switch people from B to C. Or, if you want, you can add another option Bโ, which is similar to B but with reduced animal suffering. Your favorite invertebrate welfare interventions correspond to switching people from B to Bโ, and that might at the moment be more effective than switching them from B to C.
