According to the CRAP mnemonic for dobutamine, which letter indicates no change in beta-2 activity?

Explanation:
Dobutamine acts mainly on beta-1 receptors, boosting cardiac contractility and heart rate, with little to no alpha activity. The CRAP mnemonic encodes these effects: C for increased Contractility, R for increased Rate, A for minimal Alpha activity, and P for Beta-2 activity unchanged. So the letter that indicates no change in beta-2 activity is the P component of CRAP. In this question, that meaning is represented by the option labeled D.
