Review the passage:
Each morning, Darren adds guava juice, raw egg, protein powder, raisins,
and sardines to a blender. After mixing these ingredients
on high for a few seconds, he has breakfast. A drink that will give
him plenty of energy and shiny hair.
You chose the second part, After mixing these ingredients on high for a few seconds, he has breakfast. This part has a main clause: he is the subject; has is the verb. A fragment will not have a main clause.
