Final answer:
Option (d), Ruth likely hated Isabel because she feared Isabel would leave her after finding gold, representing a fear of abandonment, but the text provided does not directly connect Ruth's feelings with the options given.
Step-by-step explanation:
The question asks why Ruth hated Isabel after they were reunited. From the provided text, it's clear that the hatred was not due to any betrayal, theft, or revealing of secrets. Instead, it appears to be based on a fear of abandonment. Bess, presumably similar to Ruth in this context, hated the thought of sharing her secret about gold with others because she was afraid it would lead to them leaving her after finding gold.
The fear of losing someone after they've gained what they want is a common human concern, but it does not necessarily equate to hatred towards the person.
