Answer:
D. Eduardo sneaks up on his mother while she's hanging laundry and scares her. She runs away in fright but returns with a good-natured threat.

This summary accurately describes what happens in the passage. His mother is obviously startled and runs away, but comes back to her son with a smirk on her face and a witty, good-natured threat to keep himon his toes. It does not specifically state that she was smiling.
