Final answer:
Option (b), where a character faces jail after committing a robbery, best supports the theme 'crime doesn't pay' by demonstrating the negative consequences of crime.
Step-by-step explanation:
The piece of text evidence that best provides support for the theme crime doesn't pay is (b) A character is arrested and jailed after she commits a robbery. This statement directly supports the theme by illustrating the negative consequence of committing a crime, hence reinforcing the idea that crime leads to undesirable outcomes, such as imprisonment. In contrast, the other options either present a new law which does not directly support the theme through a specific character's experience (a), suggest that there is no support for the theme (c), or depict crime in a positive light (d), which would contradict the theme.
