• C.
• D.

Answer: (D)

Verified step by step guidance

1. Identify the compound given: NH2NH2, which is hydrazine.
2. Understand that a conjugate acid is formed when a base gains a proton (H+).
3. Determine which nitrogen atom in NH2NH2 is more likely to accept a proton. Typically, the nitrogen with a lone pair is a good candidate.
4. Add a proton (H+) to one of the nitrogen atoms in NH2NH2, resulting in NH3NH2+.
5. The resulting formula, NH3NH2+, represents the conjugate acid of NH2NH2.
