The correct answer is
dactylic. Dactylic meter means that syllables come in groups of three: stressed
+ unstressed + unstressed, which is the way of colloquial speech sounds. In
this line the emphasis are ON a hill FAR away STOOD an old RUGGed cross.
The technique to determine
this is to put extra emphasis when reading the line in both ways, that way your
brain will automatically notice what doesn’t sound natural.
