When launching Oxyglobin:

It is better to target emergency practices only because it is more important to their practice and they would be more receptive to its benefits

It is better to target emergency practices because it would be more efficient to do so

It is better to target all veterinary practices to capture as much of the market as possible

All of these are correct

It is better to target emergency practices only because it is more important to their practice and they would be more receptive to its benefits AND it is better to target emergency practices because it would be more efficient to do so
