In a circuit with the given DC input voltages, what would the output voltage be?

In these DC op-amp style questions, the output is determined by the circuit’s transfer function. For an inverting amplifier, the output is negative and proportional to the input: Vout = - (Rf/Rin) × Vin. The negative sign shows that the stage inverts the input, and the magnitude is set by the resistor ratio. If the given DC inputs, together with the resistor values, produce a gain of 5.5, then a positive input voltage (for example +1 V) would drive the output to -5.5 V. That matches the option with the negative sign and the larger magnitude. The other numbers represent smaller magnitudes or the opposite sign and would require different input values or a different configuration, so they don’t fit the stated inputs. So, the output being -5.5 V makes sense as the result of a negative-gain transfer with the provided DC inputs.
