Why are pharmaceutical companies placing focus (such as improvements and cost reduction) on the research and development branch?

1 point

R&D is too competitive and over inflated with non-productive workers.

Better R&D means better drugs which means improved sells.

R&D always requires large attention.

R&D takes the longest and has the highest investment in the drug development cycle.
