What are the answer choices
Answer: d. Attractive
Explanation: In this sentence from "A Tale of Two Cities", based on the context, a savoury neighbourhood is an <u><em>attractive</em></u> neigbourhood. Not savoury is not pleasant or not socially acceptable. This sentence states that "Mr. Cruncher's apartments were NOT in a savoury neighbourhood" so savoury means attractive.
