The correct match is

Assertion Bt toxin exists as inactive prototoxin but once an insect ingests the inactive toxin, it is converted into an active form of toxin.
Reason Protoxin gets activated in insect gut due to the acidic in the gut, which solubilises the protein crystals.
The correct answer is:


Match the following ?
Plants | Character | Effect | |||
(a) | Flavr Savr tomato | (i) | Vit - A | (p) | Abiotic and biotic stress |
(b) | Golden rice | (ii) | Male sterility | (q) | long shell life |
(c) | Basmati rice | (iii) | Bnise resistant | (r) | Prevent blindness |
(d) | Brassica | (iv) | Resistant | (s) | Eliminate manual emasculation |

Assertion A: In Bt cotton B. thuringiensis produces a toxic insecticidal crystalline protein which destroys bollworms.
Reason R: B. thuringiensis produces this toxic protein in an inactive form, but when an insect ingests this inactive protein, it is converted into active form of toxin due to the alkaline pH of gut which solubilises the crystals, which is responsible for the death of bollworm.
