Unicellular cells must carry out all functions of life.

The correct answer is "all functions." Unicellular cells are living organisms composed of only one cell, so they must be able to carry out all the necessary functions of life within that single cell. These functions include obtaining and processing nutrients, growth and development, responding to stimuli, reproduction, and maintaining homeostasis. Unicellular organisms such as bacteria and protozoa have evolved mechanisms to perform all these essential life functions in order to survive and thrive.
