I believe that B is the answer.
<span>B. shining a bright light on the objects
and testing for decomposition </span>

In explanation, chemical property is a
characteristic of a certain substance came from an outcome due to chemical change
or reaction. In the situation above, more specifically toxicity is involved in
the chemical property/change. Hence, when the object is tested for
decomposition. Like for an example of decomposition simply in metals, rusting. Rusting
a process of degeneration of metals. Here it works the same. Toxicity is how
much damage did a certain entity do to the object. </span>
The correct answer to this is (A. Units Only).
It shows that there is a velocity of 35, but the units are missing.
P = density × gravity acceleration × height
P = 1200 × 9.81 × 15/100
P = 1765.8
