Many proteins are secreted in their inactive form. This is also true of many toxic proteins produced by microorganisms. Explain how the mechanism is useful for the organism producing the toxin ?

Many proteins including certain toxins are secreted in their inactive form. They get activated, only when exposed to a specific trigger ($pH$, temperature, etc.). It is advantageous to the bacteria producing it because the bacteria do not get killed due to the action of protein.

Given below are two statements:
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 $\mathrm{pH}$ of the insect gut.
In the light of the above statements, choose the correct answer from the options given below:
