Find the Zeros of the Polynomial Function and State the Multiplicity

Multiple Choice

Find the zeros of the polynomial function and state the multiplicity of each.
- $$( 7 x - 2 ) ^ { 4 } \left( x ^ { 2 } + 16 \right) ^ { 2 }$$

A) $\frac { 4 } { 7 }$ (multiplicity 4) , ±4i (multiplicity 2 )
B) $\frac { 2 } { 7 }$ (multiplicity 4 $) , \pm 4$ (multiplicity 2 )
C) $- \frac { 2 } { 7 }$ (multiplicity 4) , $\pm 4$ i (multiplicity 2 )
D) $\frac { 2 } { 7 } ($ multiplicity $4 ) , \pm 4 \mathrm { i } ($ multiplicity $2 )$
