The correct answer is #D#. Seee xplanation for details.

Explanation:

In the question we have the mass and the density given, and we must calculate the volume.

To do this we have to use the formula:

#d=m/V#

where #d# - density, #m# - mass and #V# - volume

After rearranging the formula we get:

#V=m/d#

Before calculations we have to check the units:

The density is given in #g/(cm^3)#, while the mass is given in #kg#. Looking at the answers we can see that we have to express the mass in grams. To do this we have to multiply the mass in kilograms by #1,000#: #m=18,754,000g#

Now we can divide the numbers to get the volume:

#V=(1,754,000)/0.788~~2.38xx10^7#
