Question

Consider the $\mathrm{OP} \mathrm{AMP} $ based circuit shown in the figure. Ignore the conduction drops of diodes $\text{D}_{1}$ and $\text{D}_{2}$.  All the components are ideal and the breakdown voltage of the Zener is $5 \mathrm{~V}.$ Which of the following statements is true? 

• A. The maximum and minimum values of the output voltage $\text{V}_{O} $ are $+15 \mathrm{~V}$ and$-10 \mathrm{~V}$, respectively. 
• B. The maximum and minimum values of the output voltage $\text{V}_{O} $ are $+5\mathrm{~V}$ and$-15 \mathrm{~V}$, respectively.
• C. The maximum and minimum values of the output voltage $\text{V}_{O}  $ are $+10 \mathrm{~V}$ and $-5 \mathrm{~V}$, respectively.
• D. The maximum and minimum values of the output voltage $\text{V}_{O} $ are $+5 \mathrm{~V}$ and $-10 \mathrm{~V}$, respectively.
