Answer:

Option D is the correct answer.

Explanation:

The specific gravity of copper is 8.91.

We have

$\frac{\texttt{Density of copper}}{\texttt{Density of water}}=8.91\\\\\texttt{Density of copper}=8.91\times 1000kg/m^3=8910kg/m^3$

We also have

1 kg = 2.205 lb

1 m = 3.28 ft

Substituting

$\texttt{Density of copper}=8910kg/m^3=\frac{8910\times 2.205}{3.28^3}=556.76lb/ft^3$

Option D is the correct answer.
