For a projection to be considered an entanglement, how much must it extend from the initial surface?

When determining if a projection is an entanglement, one must look at how much it extends from the initial surface. In this case, the extend must be more than 0.12 inches to be considered an entanglement. The other options of 1 inch, 0.5 inches, and 1.5 inches all represent distances that are larger than 0.12 inches, making them incorrect choices.
