Question

post-test
which of the following is true regarding unibody construction?
a. it is commonly used for heavy-duty trucks.
b. the body and frame are integrated into a single structure.
c. it has a separate frame that supports the body.
d. the frame is assembled around the motor, chassis sub-assemblies, and trim.

Explanation:

Unibody construction merges the vehicle's body and frame into one unified structure, which differs from body-on-frame designs (where body and frame are separate, used for heavy-duty trucks). Option A is incorrect because heavy-duty trucks use body-on-frame, not unibody. Option C describes body-on-frame, not unibody. Option D refers to a body-on-frame assembly process.

Answer:

B. The body and frame are integrated into a single structure.
