Step-by-step explanation:
The MOTIF that is present in both math and the modern story of Pygmalion and My Fair Lady is A) Transformation. This motif is central as it represents a fundamental change in the characters or situations. In the context of math, transformation can refer to a change in form or function, such as a geometric transformation like a rotation or reflection. In literature, and specifically in Pygmalion and My Fair Lady, the motif of transformation is evident in the stories' core plot of a lowly flower girl being transformed into a lady of high society through education and refinement of manners. This transformation is both a literal change in how she behaves and is perceived, as well as a metaphorical one, reflecting changes in social status and personal identity.
