B. They are genetically identical to the parent because they are produced by sexual reproduction.

C.  They are genetically identical to the parent because they are produced by asexual reproduction.

D. They are genetically different from the parent because they are produced by asexual reproduction.

Answer:

The correct answer is- C.  They are genetically identical to the parent because they are produced by asexual reproduction.

Explanation:

<em>E. coli </em>reproduces through binary fission in which the genetic material of cell of <em>E. coli</em> first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.  

After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other <em>E.coli</em> therefore the resultant daughter cells are identical to the parent cell.

Therefore the correct answer is option c.
