According to the 'Data from the Experiment' table, what was the mean plasma ACTH level at 6:00 AM for the 'Short' protocol, and what was the change Δ in ACTH level in the 30 minutes post-waking for this protocol?

  • A: 37.3 pg/mL at 6:00 AM and 10.6 pg/mL Δ in 30 minutes.
  • B: 9.9 pg/mL at 1:00 AM and 10.6 pg/mL Δ in 30 minutes.
  • C: 26.5 pg/mL at 6:00 AM and 12.2 pg/mL Δ in 30 minutes.
  • D: 25.5 pg/mL at 6:00 AM and 22.1 pg/mL Δ in 30 minutes.

Explanation

For the 'Short' protocol row in the table, the mean plasma ACTH level at 6:00 AM is 37.3 pg/mL, and the Δ in the 30 minutes post-waking is 10.6 pg/mL. Option A correctly presents these two values.
