Consider the following statements:
| I: | The VNTRs belong to a class of satellite DNA called as mini-satellite. |
| II: | Southern blotting is the transfer of DNA fragments to a filter cellulose membrane. |
| III: | VNTRs are used in DNA fingerprinting as they do not show any variations and are not inherited. |
Which of the above statements are true?
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II, and III |

| 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 |
