Answer:
B
Step-by-step explanation:
We are given the equation:

And that <em>x</em> = 2 is a root. And we want to determine the value of <em>k</em>.
By definition, since <em>x</em> = 2 is a root of the equation, when <em>x</em> = 2, the equation must equal zero:

Solve for <em>k: </em>
<em />
<em />
<em />
Hence, the value of <em>k</em> is -4.
In conclusion, our answer is B.
