E.

I. C=2D; All we have is the 7 wk total. Although C produced 2x the amount that D did, it doesn't imply that C was more efficient. Say that C produced 1,1,1,1,1,10,9 units respectively during the 7 wk span for a total of 24 units and D produced 2,2,2,2,2,1,1 for a total of 12 units.

II. Doesn't say much about a specific branch.

I & II. No good either. You can change the distributions in the above example to verify. C can have the production front loaded and thereby be declared the winner or the production can be backed loaded and it can come out the loser.
