Match the following to express general resemblance between bones and girdle fore limbs and hind limbs.

List no. 1		List no. - 2
a.	Shoulder joint	i.	Tibio-fibula
b.	Humerus	ii.	Knee
c.	Elbow	iii.	Femur
d.	Radio-ulna	iv.	Hip joint

The correct answer is Option 1.

Key Points

• The question involves matching bones and joints of the forelimbs with their analogous counterparts in the hind limbs.
• Here is the correct mapping:
  • a. Shoulder joint corresponds to iv. Hip joint
  • b. Humerus corresponds to iii. Femur
  • c. Elbow corresponds to ii. Knee
  • d. Radio-ulna corresponds to i. Tibio-fibula
• Hence, the correct answer is a - iv, b - iii, c - ii, d - i, which matches with Option 1.

Additional Information

• The shoulder joint in the forelimb and the hip joint in the hind limb are ball-and-socket joints, allowing a wide range of motion.
• The humerus in the forelimb and the femur in the hind limb are long bones that connect the girdle to the limb.
• The elbow and the knee are hinge joints, allowing flexion and extension movements.
• The radio-ulna in the forelimb and the tibio-fibula in the hind limb are fused bones that provide structural support and mobility.
