Answer:
<em>The correct option is: C) 4x(3y + 7z)</em>
Step-by-step explanation:
Given expression is: 
First we need to find the GCF(Greatest common factor) of
and
and then we will factor out that GCF.

We can see that the common factors are: 
So, the GCF will be: 
Now factoring out
from the given expression, we will get.....

So, the complete factorization will be:
