Final answer:
Tasker is addressing Mrs. Daigle in the dialogue, as the context implies a remark directed towards a female character.
Step-by-step explanation:
In the dialogue provided, Tasker is addressing the character of Mrs. Daigle. The given script excerpts are from 'A Doll's House' by Henrik Ibsen and do not include a character named Tasker; however, the context indicates that Tasker would be making an affectionate remark to a female character. Given the options, the one who fits this characterization would be Mrs. Daigle, as Tasker would not be addressing Rhoda, Christine, or Leroy with such an endearment.
