Question

Match the following:

List - I		List - II
A.	Skeletal system	I.	Lungs
B.	Muscular system	II.	Deltoid, Abdomen
C.	Circulatory system	III.	Bone, Joints
D.	Respiratory system	IV.	Heart

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

Hint:

Bones and joints form the skeletal system, muscles produce movement, the heart pumps blood, and lungs help in respiration.

Answer 1

The Correct Option is B

Concept: Different body systems are associated with specific organs and structures that perform specialized functions.
• Skeletal system -- provides support and structure through bones and joints.
• Muscular system -- responsible for body movement through muscles.
• Circulatory system -- transports blood through the heart and blood vessels.
• Respiratory system -- involved in breathing through organs such as lungs.

Step 1: Match each system with its related structure.
\[ \begin{aligned} \text{Skeletal system} &\rightarrow \text{Bone, Joints} \text{Muscular system} &\rightarrow \text{Deltoid, Abdomen} \text{Circulatory system} &\rightarrow \text{Heart} \text{Respiratory system} &\rightarrow \text{Lungs} \end{aligned} \]

Step 2: Write the correct matching sequence.
Thus, the correct matching is: \[ A-III,\ B-II,\ C-IV,\ D-I \] Hence, the correct answer is: \[ \boxed{(B)\ A\text{-}III,\ B\text{-}II,\ C\text{-}IV,\ D\text{-}I} \]
