Can I have another explanation as to why option C is incorrect? Thank you.

@Adri Maybe I can help. Let's take a look.

We can break the passage down as follows:
Premise: In some experiments, genetic mutations occured at random.
Premise: Missing - this is what we the answer choice we are looking for will provide.
Conclusion: All genetic mutation is random.

So, we are looking for the second premise that will connect the idea that "genetic mutations occured at random in some experiments" to the idea that "all genetic mutation is random." Answer choice (A) does this, as Mehran explains in the video.

(C) is incorrect because it does not provide the missing link. Instead, it creates a new S->N statement based on the Sufficent condition "IF all genetic mutations in bacteria are random." Note that answer choice (C) only sets up a hypothetical "IF" statement. It does not state anything definitively about genetic mutations that would be helpful in connecting our premise to our conclusion. Therefore, it is irrelevant and incorrect.

Does this make sense? Please let us know if you have any other questions!
