The correct answer is B.
EXPLANATION
The multiplicity simply tells us how many times the roots repeat or how many times the factor multiplies itself in the polynomial.
[tex](x+4)[/tex] is multiplying itself three times, so its root -4 has multiplicity of 3.
[tex](x-10)[/tex] repeats once so its root 10 will have a multiplicity of 1.
Also, for the leading coefficient to be 2 then the constant factor should be 2.
Hence the correct answer is option B
