post-test
crown refers to:
a. the shape steel takes before the point of tensile failure.
b. the curvature and shape of a sheet metal body panel.
c. the shape steel takes when it is heated to high temperatures.
d. the shape of a minor aluminum metal panel dent.

Explanation:

In the context of sheet metal (related to engineering, a subfield of Natural Science), "crown" refers to the curvature and shape of a sheet metal body panel. Option A is about tensile failure shape, C about heated steel shape, D about an aluminum dent shape—none match the definition of crown for sheet metal.

Answer:

B. The curvature and shape of a sheet metal body panel.
