Final answer:
Pearl is cautioning Jed to be wary of city strangers who carry C) satchels, implying that such individuals might be deceitful and should not be trusted.
Step-by-step explanation:
Pearl is warning Jed about trusting strangers with C) satchels. Pearl's use of the word 'slicker' suggests that she believes these individuals are likely to be deceitful or swindlers.
From the context given, it is clear that Pearl associates carrying a satchel with city folk who might have questionable intentions and whom she deems untrustworthy, potentially trying to cheat or outsmart them. This interpretation is in line with the themes often explored in western literature, where a sharp divide between the trustworthiness of city vs. country folk is frequently depicted.
