Final answer:
The mother feels annoyed with her daughter's request to finish the soup based on her curt response, suggesting she is in no mood for what she sees as her child's reluctance or games.
Step-by-step explanation:
Basing on the text provided, the mother perceives her daughter's request to finish her soup with annoyance. As indicated in Clinical Focus Part 1, the mother's curt reply to her daughter's complaint about the soup being too slimy suggests she is not in the mood for what she considers games. Her tone and the use of the word 'curtly' imply that she is feeling irritated and perhaps impatient with her daughter's reluctance to finish her lunch, thus pointing to option (a) She feels annoyed by her daughter's request. This emotional response could be due to stress or other factors not detailed in the snippet provided, but clearly, the mother's emotional state is one of annoyance.
