Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:

We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.
Moreover we can also note that all the other quadratic expressions can be factorized ..
