Given below are two statements : 
Statement I: Proteins encoded by genes cryIAc and cryllAb control corn borer, that of crylAb control the cotton bollworms 
Statement II: Bt toxin protein exist as inactive protoxins but once an insect ingests the inactive toxin, it is converted into an active form of toxin due to the alkaline pH of the gut 
In light of the above statements, choose the most appropriate answer from the options given below:
1. Both Statement I and Statement II are true 
2. Both Statement I and Statement II are false 
3. Statement I is true and Statement II is false 
4. Statement I is false but Statement II is true
