Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

$\mathrm{L}$-isomer of a compound${}^{\text{'}}\mathrm{A}^{\text{'}}\left({\mathrm{C}}_4{\mathrm{H}}_8{\mathrm{O}}_4\right)$gives a positive test with${\left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]}^{+}$. Treatment of '$\mathrm{A}$' with acetic anhydride yields triacetate derivative. Compound '$\mathrm{A}$' produces an optically active compound$\left(\mathrm{B}\right)$and an optically inactive compound$\left(\mathrm{C}\right)$on treatment with bromine water and${\mathrm{HNO}}_3$respectively. Compound$\left(\mathrm{A}\right)$is :
