**Resonance Structures of Compound 1**

The image provided contains a multiple-choice question and three potential resonance structures.

**Question:**
Which of the following are resonance structures of compound 1?

**Displayed Compound 1:**
- The compound 1 is in a box and drawn with the following structure:
  - A nitrogen atom (N) bonded to a carbon atom (C).
  - The nitrogen is also bonded to two hydrogen atoms (H).
  - The carbon is double-bonded to an oxygen atom (O) with two lone pairs of electrons and single-bonded to a hydrogen atom (H).

**Potential Resonance Structures:**

**Option A:**
- A nitrogen atom (N) bonded to a carbon atom (C).
  - The nitrogen has a double bond with a carbon atom.
  - The nitrogen also has two lone pairs of electrons.
  - The carbon is single-bonded to an oxygen atom (O) with three lone pairs of electrons.
  - The carbon is additionally bonded to a hydrogen atom (H).

**Option B:**
- A nitrogen atom (N) bonded to a carbon atom (C).
  - The nitrogen has a single bond with a carbon atom and three lone pairs of electrons.
  - The carbon is double-bonded to an oxygen atom (O) with two lone pairs of electrons.
  - The carbon is bonded to a hydrogen atom (H).
  - The compound carries an overall negative charge.

**Option C:**
- A nitrogen atom (N) bonded to a carbon atom (C).
  - The nitrogen has a positive charge with a single bond to a carbon atom and one lone pair of electrons.
  - The carbon is double-bonded to an oxygen atom (O) with two lone pairs of electrons.
  - The carbon is bonded to a hydrogen atom (H).
  - The compound carries an overall positive charge.

**Explanation of Resonance Structures:**
Resonance structures depict the delocalization of electrons within molecules. They are different Lewis structures for the same molecule that represent the same arrangement of atoms but different arrangements of electrons. Each resonance structure shows possible distributions of electron density within the molecule, highlighting areas of potential electron movement. The actual molecule is a hybrid of these resonance structures, meaning it exhibits characteristics of each contributing form.
