• B. i, ii are wrong
• C. ii, v are wrong
• D. iii and iv are wrong

Answer 1

Answer: (D)

iii and iv are wrong

• The patella or kneecap, is a thick, circular-triangular bone which articulates with the femur (thigh bone).
  
• It covers and protects the anterior articular surface of the knee joint.
  
• Each half of pectoral girdle consists of a clavicle and a scapula. The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs. Hence scapula is present on the ventral side of the thorax.
• So, the correct answer is 'iii and iv are wrong'.
