Given below are two statements:
In the light of the above statements, choose the correct answer from the options given below:
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. |
In the light of the above statements, choose the correct answer from the options given below:
1. Both Statement I and Statement II are False
2. Statement I is True but Statement II is False
