Options
- AA-III, B-IV, C-II, D-I
- BA-IV, B-III, C-I, D-II
- CA-IV, B-III, C-II, D-I
- DA-III, B-IV, C-I, D-II
Correct answer
C. A-IV, B-III, C-II, D-I
Step-by-step solution
According to NCERT, skeletal muscle is made of a number of muscle bundles or fascicles held together by a common collagenous connective tissue layer called fascia. The sarcoplasmic reticulum of the muscle fibres is the storehouse of calcium ions. The portion of the myofibril between two successive Z-lines is considered the functional unit of contraction and is called a sarcomere. Therefore, the correct matching is A-IV, B-III, C-II, D-I. Answer: A-IV, B-III, C-II, D-I
