A
Explanation:
It's the sentence that has the most reflective elements
In the play Pygmalion, the flower girl says this. It "translates" to:
"Oh, he's your son, is he? Well, if you'd done your duty as a mother should, he'd know better than to spoil a poor girl's flowers, then run away without paying! Will you pay for them?"
She says this to the mother of the boy who recently knocked her flowers down and trampled them. She says this because she wants to be compensated for the ruined flowers.
