List I Name of the drug		List II Chemical class
A.	Zolpidem	I.	Cyclopyrrolone
B.	Zaleplon	II.	Benzodiazepine
C.	Zopiclone	III.	Imidazopyridine
D.	Triazolam	IV.	Pyrazolopyrimidine

Choose the correct answer from the options given below

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

Answer 1

The Correct Option is C

Let's match the drugs in List I with their corresponding chemical classes from List II. We are given the following drugs and chemical classes: 

Name of the drug	Chemical class
A. Zolpidem	I. Cyclopyrrolone
B. Zaleplon	II. Benzodiazepine
C. Zopiclone	III. Imidazopyridine
D. Triazolam	IV. Pyrazolopyrimidine

Let's match them step-by-step:

1. Zolpidem: Zolpidem is an Imidazopyridine. It is used as a sedative or hypnotic for the short-term treatment of insomnia. Hence, it belongs to the chemical class III. Imidazopyridine.
2. Zaleplon: Zaleplon falls under the category of Pyrazolopyrimidine. It is also used for treating insomnia with a very short half-life. Therefore, it belongs to the chemical class IV. Pyrazolopyrimidine.
3. Zopiclone: Zopiclone is classified as a Cyclopyrrolone. It is used as an hypnotic agent for insomnia. Therefore, it belongs to the chemical class I. Cyclopyrrolone.
4. Triazolam: Triazolam is a Benzodiazepine. It is commonly used to treat severe insomnia on a short-term basis. Consequently, it belongs to the chemical class II. Benzodiazepine.

Based on these classifications, the correct matching of List I with List II is:

• A-III: Zolpidem - Imidazopyridine
• B-IV: Zaleplon - Pyrazolopyrimidine
• C-I: Zopiclone - Cyclopyrrolone
• D-II: Triazolam - Benzodiazepine

Thus, the correct answer is: A-III, B-IV, C-I, D-II.
