Oh no! You got this question incorrect.
No worries! I'll explain how to properly answer this question.
In order to answer these questions you must remember that a conjugate acid gains a proton (H+) and a conjugate base looses a proton. Question: What is the conjugate acid in this equation: NH₃(g) base + H₂O(l) base --> NH₄⁺(aq) Conjugate acid + OH⁻ (aq) Conjugate base In this equation, NH₃ gains a proton and forms NH₄. This means that NH₃ is an base and NH₄ is a conjugate acid. In addition to this, the H₂O looses a proton and forms OH⁻. This means that in this equation, H₂O is an acid and OH⁻ is a conjugate base.
