Predicate adjective and direct object
A simile is first defined as a type of speech that uses one thing or
phrase with comparisons to things of an unrelated kind, often in order
to make a more vivacious description. So of the phrases above, only the
last one (I swear she cast a shadow white as stone) would be considered a
simile, as a shadow white as stone takes two unrelated things and uses
them in an interesting way.
It is A because it complete the sentence "She has given five short speeches as practice"
All of the above hope this helps
