Question

Read the passage below and answer the question that follows.

The drawing-room was silent save for the mantel clock, a gilded bronze monstrosity of the late empire, which did not so much tick as shudder. Its pendulum swung with a frantic, uneven velocity, as though trying to outrun its own mechanism, only to catch itself with a metallic gasp at the apex of each arc. Clara watched it from the velvet chaise, her fingers tracing the stiff, embroidered gold thread of her collar. The collar was fashionably high, binding her throat so tightly that each breath felt like a minor negotiation with the linen. Outside, the London fog pressed against the windowpanes, a heavy, yellow wool that muffled the rattle of passing carriages and turned the gas lamps into distant, drowning eyes. Clara looked back at the clock’s face. The hands were delicate, wrought-iron arrows, but they pointed stubbornly between the hours, refusing the precision of the Roman numerals. To Clara, the erratic rhythm was not a failure of craftsmanship but a silent rebellion against the house’s suffocating order—the silver service polished to a blinding sheen, the portraits of her husband’s ancestors staring down with dead, varnished eyes, and the schedule of calls that mapped out her life like a railway timetable. When the heavy oak door downstairs clicked open, announcing her husband’s return, the clock seemed to hesitate, its pendulum frozen for one long, agonizing beat before resuming its frantic, disjointed race.

In the passage, the erratic movement of the mantel clock’s pendulum functions primarily to symbolize which of the following?
