Answer:

The correct answer is - option 1, and option 3.

Explanation:

Bacillus Thuringiensis is a type of Gram-positive, soil-dwelling bacterium. This bacterium is normally used as pesticides. Bacillus cereus is a soil bacterium and a human pathogen that is very opportunistic and easily infects the humans.

The only difference between these two species is in the genes that code for the insecticidal toxins. These genes are present on plasmids. As they are from the same genus where is other options are all different and there is only a change in genes that express one quality.

Thus, the correct answer would be - option 1 and option 3.
