In the given reaction:
\[ NH_2^- + CH_3OH \rightarrow NH_3 + CH_3O^- \]
A Brønsted-Lowry base is defined as a substance that accepts a proton (H⁺).
In this reaction, the species that acts as a Brønsted-Lowry base is the **NH2− (amide ion)** because it accepts a proton from **CH3OH (methanol)**, resulting in the formation of **NH3 (ammonia)**.
Therefore, the correct answer is:
**NH2− (cap n cap h sub 2 raised to the negative power)**.
\[ NH_2^- + CH_3OH \rightarrow NH_3 + CH_3O^- \]
