An Experimenter Shows a Child Two Clay "Sausages" That Are

An experimenter shows a child two clay "sausages" that are identical in size and shape and then allows the child to watch as she rolls one of the clay sausages into a longer, thinner sausage. The experimenter then asks
the child whether the two clay sausages still contain the same amount of clay. A child in Piaget's preoperational stage would be MOST likely to say:

A) "Yes, they have the same amount of clay."
B) "No, the longer sausage has more clay than the shorter sausage."
C) "No, the shorter sausage has more clay than the longer sausage."
D) "Wait, I don't understand. How did you make that sausage bigger?"
E) A child in the concrete operational stage would not be able to answer the question as he or she would not yet understand size comparisons.
