A gerund has a -ing at the end, so A. toes and C. touched could not be gerund.
Among the other two options, B. stretching and D. running Stretching is a present participle (a verbal form) and running - a noun- is a gerund, since gerunds are nouns.

illustrator
Illustrators. By definition, illustrators demonstrate the verbal messages they accompany. Waving a hand to say "hello" is an example of an illustrator. Illustrators are also used to communicate dimensions or direction. When asked to describe the length or width of an object, a person might hold out her hands or separate her thumb and forefinger to illustrate the measurement.
