Read the passage from "Two Kinds.”

She walked over and stood in front of the TV. I saw her chest was heaving up and down in an angry way.

"No!” I said, and I now felt stronger, as if my true self had finally emerged. So this was what had been inside me all along.

"No! I won’t!” I screamed.

She yanked me by the arm, pulled me off the floor, snapped off the TV. She was frighteningly strong, half pulling, half carrying me toward the piano as I kicked the throw rugs under my feet. She lifted me up and onto the hard bench. I was sobbing by now, looking at her bitterly. Her chest was heaving even more and her mouth was open, smiling crazily as if she were pleased I was crying.

"You want me to be something that I’m not!” I sobbed. "I’ll never be the kind of daughter you want me to be!”

"Only two kinds of daughters,” she shouted in Chinese. "Those who are obedient and those who follow their own mind! Only one kind of daughter can live in this house. Obedient daughter!”

Which statement best explains the motivation for the actions of the narrator’s mother?

She is extrinsically motivated by fear of having wasted money on a piano that no one plays.
She is extrinsically motivated by her anger over her daughter’s television-viewing practices.
She is intrinsically motivated by her love of piano music to get her daughter to practice playing.
She is intrinsically motivated by her belief that children should obey their parents.

Only one of those makes real sense.

Be sure you are clear on the difference between "extrinsically" and "intrinsically" — https://www.onelook.com

The passage suggests that the motivation for the actions of the narrator's mother is that she is intrinsically motivated by her belief that children should obey their parents. This can be seen in her statement, "Only two kinds of daughters... obedient daughter!" This indicates that the mother's actions are driven by her desire for her daughter to conform to her expectations and be obedient.
