Match the enzyme in column I with its function in column II and choose the correct option. $\begin{array}{|l|l|} \hline \text{Column I} & \text{Column II} \\ \hline \text{A. } \beta-\text{galactosidase} & 1. \text{Joining of DNA fragments} \\ \hline \text{B. Permease} & 2. \text{Peptide bond formation} \\ \hline \text{C. Ligase} & 3. \text{Hydrolysis of lactose} \\ \hline \text{D. Ribozyme} & 4. \text{Increases permeability to } \beta-\text{galactosidase} \\ \hline \end{array}$

• A

  $\begin{array}{l|l|l|l} A & B & C & D \\ \hline 2 & 1 & 4 & 3 \end{array}$
• Correct answer
  B

  $\begin{array}{l|l|l|l} A & B & C & D \\ \hline 3 & 2 & 1 & 4 \end{array}$
• C

  $\begin{array}{l|l|l|l} A & B & C & D \\ \hline 2 & 4 & 1 & 3 \end{array}$
• D

  $\begin{array}{l|l|l|l} A & B & C & D \\ \hline 1 & 2 & 4 & 3 \end{array}$

Hence, the correct answer is option: 'B'.
