Defining transformations

CCSS.Math: HSG.CO.A.4

Google Classroom

Tony tried to define a translation.

Point A maps to point A, prime.
Every point P maps to point P, prime such that P, P, prime, with, \overrightarrow, on top is parallel to A, A, prime, with, \overrightarrow, on top and points in the same direction as A, A, prime, with, \overrightarrow, on top.

What mistake did Tony make in his definition of a translation?

(Choice A)
Tony needed to mention that the center of translation maps to itself.
(Choice B)
start overline, P, P, prime, end overline must have the same length as start overline, A, A, prime, end overline.
(Choice C)
P, P, prime, with, \overrightarrow, on top must be perpendicular to A, A, prime, with, \overrightarrow, on top.
(Choice D)
Tony did not make a mistake.
