Find the Zeros of the Polynomial Function and State the Multiplicity

Find the zeros of the polynomial function and state the multiplicity of each.
$f ( x ) = \left( x ^ { 2 } + x - 12 \right) ^ { 6 } ( x - 2 + \sqrt { 7 } ) ^ { 2 }$

A) $- 4,3 \text { (multiplicity 6) , } 2 - \sqrt { 7 } \text { (multiplicity } 2 \text { ) }$
B) $- 4,3 \text { (multiplicity 6) , } 2 + \sqrt { 7 } \text { (multiplicity 2) }$
C) $- 4 , - 3 \text { (multiplicity } 6 ) , - 2 - \sqrt { 7 } \text { (multiplicity } 2 \text { ) }$
D) $4 , - 3 \text { (multiplicity } 6 \text { ) , } 2 - \sqrt { 7 } \text { (multiplicity } 2 \text { ) }$
