Final answer:
The atom with the lowest attraction towards electrons is Li, as it has the lowest electronegativity.
Step-by-step explanation:
The atom with the lowest attraction towards electrons is the one with the lowest electronegativity. Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. In this case, the atom with the lowest electronegativity is Li, which has a lower electronegativity value compared to C, F, and Br. Therefore, the correct answer is D) Li.
