Answer:
A
Explanation:
B is incorrect because asexual reproduction produces an offspring exactly the same as it's parent. Thus the probability does not need to be calculated.
C and D logically do not make sense since B is incorrect and A is correct. I provided the explanation why it is incorrect above.
Thus A is the correct answer.
