Question

Match the entries in Group I (Mechanical system) with analogous quantities in Group II (Electrical system) 
Group I                                  Group II 
P) Proline                          1) Artificial sweetener 
Q) Oxytocin                      2) Cyclic amino acid 
R) Aspartame                   3) β-Lactam 
S) Penicillin                      4) Peptide hormone 
 

• A. P-2, Q-4, R-1, S-3
• B. P-3, Q-1, R-4, S-2
• C. P-4, Q-3, R-1, S-2
• D. P-2, Q-1, R-4, S-3

Hint:

Remember that peptide hormones are often related to small peptides like oxytocin, while amino acids like proline form part of proteins.

Answer 1

The Correct Option is A

Step 1: Understanding the entries. 
- Proline (P) is a cyclic amino acid (Group II, 2). 

- Oxytocin (Q) is a peptide hormone (Group II, 4). 

- Aspartame (R) is an artificial sweetener (Group II, 1). 

- Penicillin (S) is a β-lactam (Group II, 3). 
 

Step 2: Conclusion. 
The correct answer is (A) P-2, Q-4, R-1, S-3, as it matches the correct categories.
