Calculate the density:

[tex]m=8.97 \ g \\ V=0.79 \ cm^3 \\ \\ \rho=\frac{m}{V}=\frac{8.79 \ g}{0.79 \ cm^3} \approx 11.35 \ \frac{g}{cm^3}[/tex]

It's the density of lead, so the answer is C.

Answer: The correct option is Option C.

Explanation:

To identify the sample, we will determine the density of the unknown sample and match it with the specific densities. The equation used to calculate the density of a sample is given by:

[tex]Density=\frac{Mass}{Volume}[/tex]

We are given:

Mass of the sample = 8.97 g

Volume of the sample = [tex]0.79cm^3[/tex]

Putting values in above equation, we get:

[tex]\text{Density of the sample}=\frac{8.97g}{0.79cm^3}=11.35g/cm^3[/tex]

This value of density matches the specific density of lead.

Hence, the correct option is Option C.
