Final answer:
The correct synonym for 'crumb' in the context of the sentence is 'portion', which represents a small fragment of the whole.
Step-by-step explanation:
The question you've asked is related to identifying synonyms in English. The sentence provided uses the word 'crumb', which generally refers to a small fragment of bread or food. In the context provided, it seems to signify a small portion or fragment of something larger—metaphorically referring to a small piece of law.
The answer choices are Chunk, Portion, Piece, and Whole. Considering the context, the correct synonym for 'crumb' would be 'portion' as it best represents a fragment of the whole. The options 'piece' and 'chunk' can be considered synonyms too, but they might imply a slightly larger fragment than 'crumb'. 'Whole', on the other hand, is the antonym of 'crumb', signifying the complete entity as opposed to a part.
