Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | Shortening of myofilaments leads to the shortening of the muscle. |
| Reason (R): | Only the actin myofilaments shorten while the length of the myosin myofilaments remains the same during the muscle shortening. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |

Classification of joints is done on the basis of:
| I: | the connective tissue that binds the bones together |
| II: | the degree of motion at each joint |
| III: | the number of bones that articulate with each other |

| 1. | I, II and III | 2. | II and III |
| 3. | I, II, III and IV | 4. | I and II |
