Answer: D) Banquo values his own morals more than he values power or wealth.
Step-by-step explanation: In the given information from the start of Act II of "Macbeth" by William Shakespeare we can see that when Macbeth asks Banquo to support him in the following days (in exchange of a reward), Banquo agrees, but he makes clear that he will only support Macbeth as long as his conscience lets him, so according to that last part, we can know that Banquo values his own morals more than he values power or wealth (he only wants the reward if he has a clear conscience too).
