Answer:
Mrs. Pearce is Higgins housekeeper.
Explanation:
George Bernard Shaw's "Pygmalion" is a comical story about a street girl named Eliza Doolittle and how she underwent an experiment to better herself. The story delves into the themes of identity, society, appearance, language, transformation, etc.
Professor Henry Higgins and Colonel Pickering are the two individuals who had decided to try to change or experiment on Eliza, to transform her into a class higher through her speech. And in Act II, we get to meet Mrs. Pearce, who is Higgins' housekeeper. This is explicitly mentioned in the stage direction/ in parenthesis <em>"[Mrs. Pearce looks in: she is Higgins’s housekeeper]"</em> when she came to announce the arrival of Eliza at Higgins' laboratory.
Thus, the correct answer is the second option.
