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 pH of the insect gut.
In the light of the above statements, choose the correct answer from the options given below:

(1). Statement I is true but Statement II is false
(2). Statement I is false but Statement II is true
(3). Both Statement I and Statement II are true
(4). Both Statement I and Statement II are false

(2). Gene isolated from marrow cells producing ADA is introduced into cells at embryonic stages
(3). Lymphocytes from patient's blood are grown in culture, outside the body
(4). Genetically engineered lymphocytes are not immortal cells.
