Question

when using a portable band saw, what should the stop be placed firmly against?
bench surface
miter box fence
trigger lock
object being cut

Explanation:

When using a portable band - saw, the stop is placed firmly against the object being cut to ensure accurate and consistent cuts. A bench surface is not relevant for this purpose. A miter box fence is used for miter cuts in a miter box and not related to the stop of a portable band - saw. The trigger lock is for safety to prevent accidental starting and not what the stop is placed against.

Answer:

D. object being cut
