The correct answer is A. (i) and (iii).

A scissors cross-over is a type of knot that is formed by crossing two strands of rope in an X-shape. The crossings in a scissors cross-over are all obtuse angles, as shown in the diagram below.

There are two obtuse angle crossings in each scissors cross-over, as shown by the red arrows in the diagram. There are no acute angle crossings in a scissors cross-over.
