Among the following Cr(III) complexes, which one will have the highest octahedral crystal field splitting?

Which one among the following is a semi-synthetic polymer?

Considering the facts that

I. sucrose forms glycosidic linkage between $\mathrm{C}_1$ of glucose and $\mathrm{C}_2$ fructose, while

II. lactose forms glycosidic linkage between $\mathrm{C}_1$ of galactose and $\mathrm{C}_4$ of glucose.

Choose the correct statement.

$$ \text { Match the following : } $$

$$ \begin{array}{llll} \hline & \text { List-I } & & \text { List-II } \\ \hline \text { A. } & \text { Codeine } & \text { I. } & \text { Antiseptic } \\ \hline \text { B. } & \text { Dettol } & \text { II. } & \text { Antibiotic } \\ \hline \text { C. } & \text { Tetracycline } & \text { III. } & \text { Narcotic analgesics } \\ \hline \end{array} $$

$$ \text { The correct match is } $$
