236. (A) Macbeth resolves to challenge fate \textit{"to the utterance"} because he believes it is the only way to secure his kingship against Banquo's descendants.
(R) Macbeth acknowledges that he has already sacrificed his soul (\$ \text{eternal jewel} \$) to the devil (\$ \text{common enemy of man} \$) to ensure Banquo's lineage becomes kings.
Key Concept: Macbeth's psychological conflict and motivation for Banquo's murder
b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.
[Solution Description]
The Assertion states that Macbeth decides to fight fate to secure his position, which is true as he says, \textit{"Rather than so, come fate into the list. And champion me to the utterance!"} in Act III, Scene 1. The Reason claims that Macbeth admits to selling his soul to make Banquo's descendants kings, which is also true as he reflects, \textit{"I have sold my immortal soul to the devil to make the descendants of Banquo kings."} However, the Reason does not explain why Macbeth challenges fate; rather, it highlights his earlier misguided actions. Thus, both are true, but the Reason is not the correct explanation of the Assertion.
