Question

Match List I with List II :

List - I		List – II
A.	Residual Volume	i.	Maximum volume of air that can be breathed in after forced expiration
B.	Vital Capacity	ii.	Volume of air inspired or expired during normal respiration
C.	Expiratory Capacity	iii.	Volume of air remaining in lungs after forcible expiration
D.	Tidal Volume	iv.	Total volume of air expired after normal inspiration

Choose the correct answer from the options given below :

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

Answer 1

The Correct Option is C

To solve the given matching problem, let's understand each term from List I and match it with its correct definition from List II:

1. Residual Volume: This is the volume of air remaining in the lungs after a forcible expiration. Therefore, it matches with iii.
2. Vital Capacity: This is the maximum volume of air that can be breathed in after forced expiration. Thus, it matches with i.
3. Expiratory Capacity: This is the total volume of air expired after a normal inspiration. So, it matches with iv.
4. Tidal Volume: This is the volume of air inspired or expired during normal respiration, which matches with ii.

Based on the explanations above, the correct match and hence the answer is:

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

Let's ensure all other options can be ruled out:

• A-IV, B-III, C-II, D-I: This arrangement incorrectly places terms, mismatching definitions.
• A-II, B-IV, C-I, D-III: This option incorrectly connects the terms, leading to incorrect matches as per their definitions.
• A-I, B-II, C-III, D-IV: This option completely mismatches all terms with their definitions.

Thus, after ruling out the incorrect options, the valid and correct answer that aligns with the definitions and understanding of respiratory volumes is A-III, B-I, C-IV, D-II.
