Answer:

d) F⁻

Step-by-step explanation:

An anion is an ion that has a net negative charge. Ions such as OH⁻, NO₃⁻ or Cl⁻ are anions.

Monatomic means that it is made of only one atom. Mono=one. Ions such as H⁺, Na⁺ or S²⁻ are monoatomic, whereas ions such as OH⁻, NH₄⁺ or CN⁻ are polyatomic.

With this information in mind, the option that is both monatomic and an anion is d), F⁻.
