| Statement I: | Locomotory structures need not to be different from those affecting other types of movements. |
| Statement II: | All movements are locomotions, but not all locomotions are movements. |

A. Amoeboid movements
B. Ciliary movements
C. Muscular movements
| 1. | Only A | 2. | Only A and B |
| 3. | Only A and C | 4. | A, B and C |
| I: | Macrophages in body and leucocytes in blood exhibit amoeboid movement. |
| II: | Passage of ova through the female reproductive tract is facilitated by the ciliary movement. |
| III: | Human sperm moves with the help of flagellum |
| I: | Amoeboid |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle. |
| Reason (R): | Smooth muscle is an involuntary non-striated muscle. |
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. |
