347686 Select the correct answer
I. Bt toxin protein exist as inactive protoxins in the bacteria.
II. Once an insect ingest the inactive toxin, it is converted into an active form of toxin due to the acidic \(\mathrm{pH}\) of the gut which solubilise the crystals.

1 Only I is correct
2 Only II is correct
