The correct option is
A What are the qualities that chefs and astronauts share?
Compare and Contrast essays examine how things are similar, or how they differ.
Option A: The title mentions common qualities of 'chefs' and 'astronauts'.Hence, the best way to write the essay is Compare and Contrast.
Such a type of essay will compare the options, 'chef's qualities' and 'astronaut's qualities'. It would also bring out their differences. This is most suitable as the title is a comparison between two things.
Hence option A is correct.
Options B, C and D: These titles are fit for a descriptive essay.
These titles cannot compare and contrast, as they're each based on one thing.
Hence options B, C and D are wrong.
