Consider the values reported for total solids (144 mg/L), Iron (0.01 mg/L) and Calcium (15.3 mg/L).

It is true that:

A: The concentration of total solids expressed with two significant figures is 1.44 * 10^2mg/L and while the concentration of Iron in u g/L (micrograms/liter) is 10 u g/L

B: The concentration of calcium expressed in g/L with two significant figures is 15 g/L

C: The concentration of Iron in u g/L (micrograms/liter) is 10 and the concentration of calcium expressed in g/L is 0.153g/L.

D: The concentration of total solids expressed in g/l with two significant figures is 14 * 10^1
