Bt toxin protein that can kill many insects, doesn't kill the Bacillus because:
| 1. | Bt toxin requires acidic pH for activation |
| 2. | Bacillus has protective mechanism against it |
| 3. | In Bacillus, it is present in an inactive state and once insects ingests it, it is converted to active form |
| 4. | The protoxin requires protein conjugate for its activation |

1. Both Statement I and Statement II are False
2. Statement I is True but Statement II is False
3. Statement I is False but Statement II is True
4. Both Statement I and Statement II are True
| Statement I: | Bt toxins are insect group specific and coded by a gene cry IAc. |
| Statement II: | Bt toxin exists as inactive protoxin in B. thuringiensis. However, after ingestion by the insect, the inactive protoxin gets converted into active form due to acidic pH of the insect gut. |
