Final answer:
Mrs. Burling in 'An Inspector Calls' does not criticize Arthur Burling directly for any of the options given, but rather is critical about his manners and conduct, especially regarding his anticipation of a knighthood.
Step-by-step explanation:
In J.B. Priestley's play An Inspector Calls, Mrs. Burling criticizes her husband, Arthur Burling, for his perceived lack of manners when he expresses his pride over the possibility of acquiring a knighthood. There isn't direct criticism of his business acumen, treatment of Eva Smith, or his disregard for social class distinctions. Neither is she shown criticizing him explicitly for his involvement in Eva Smith's death, although she is critical of the behaviors of others in her family regarding the event. The correct answer to the question, considering Mrs. Burling's attitude towards her husband's demeanor and propriety, is not explicitly mentioned among the options provided, indicating that the question might be missing the correct choice or is seeking a specific event not directly mentioned.
