Question

Match the LIST-I with LIST-II. 
 \[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Increased $\beta$ – Lipoproteins} & I. \ \text{Very Low Density Lipoproteins} \\ B. \ \text{Increased $\beta$ and Pre- $\beta$ Lipoproteins} & II. \ \text{Intermediate Density Lipoproteins} \\ C. \ \text{Broad $\beta$ – Lipoproteins} & III. \ \text{Low Density Lipoproteins} \\ D. \ \text{Increased Pre $\beta$ – Lipoproteins} & IV. \ \text{Low Density Lipoproteins and VLDL} \\ \hline \end{array} \]

• A. A - IV, B - II, C - III, D - I
• B. A - IV, B - III, C - II, D - I
• C. A - I, B - IV, C - II, D - III
• D. A - III, B - IV, C - II, D - I

Hint:

Remember: LDL = $\beta$, VLDL = Pre-$\beta$, IDL = Broad $\beta$ lipoproteins.

Answer 1

The Correct Option is D

Step 1: Recall the classification of lipoproteins.
- $\beta$ lipoproteins = Low Density Lipoproteins (LDL)
- Pre-$\beta$ lipoproteins = Very Low Density Lipoproteins (VLDL)
- Broad $\beta$ lipoproteins = Intermediate Density Lipoproteins (IDL)
- Combination of $\beta$ and Pre-$\beta$ suggests presence of both LDL and VLDL.
Step 2: Match them correctly.
- A. Increased $\beta$ lipoproteins $\rightarrow$ LDL (III).
- B. Increased $\beta$ and Pre-$\beta$ lipoproteins $\rightarrow$ LDL + VLDL (IV).
- C. Broad $\beta$ lipoproteins $\rightarrow$ IDL (II).
- D. Increased Pre-$\beta$ lipoproteins $\rightarrow$ VLDL (I).
Step 3: Conclusion.
The correct match is: A - III, B - IV, C - II, D - I.
