To find the mass of the nugget, we can use the formula:

density = mass / volume

We are given the density as 19.3 g/cm3 and the volume as 0.00369 L. However, the units are not compatible, so we must convert the volume to cubic centimeters (cm3) using:

1 L = 1000 cm3

0.00369 L = 0.00369 x 1000 cm3 = 3.69 cm3

Now we can rearrange the formula to solve for the mass:

mass = density x volume
     = 19.3 g/cm3 x 3.69 cm3
     = 71.217 g
     
Rounded to one decimal place, the mass of the nugget is 71.2 g, which corresponds to choice letter A.
