Answer:

The correct answer is "two".

Explanation:

The main bondings that has an effect in a Lewis structure in NO2Cl are the double bondings occurring between the Oxygen atoms and the Nitrogen atom. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it. I attached an example of two equivalent Lewis structure corresponding to a NO2 molecule.

Three resonance forms that contribute to the bonding in NO2Cl which are shown in the image atached.

In some compounds, a single Lewis structure does not suffice in explaining the properties of the compound. In such compounds, bonding is explained in terms of a number of structures called resonance structures.

The significant structures are those structures in which there is the lowest formal charges on atoms and minimum charge separation. There are three resonance forms that contribute to the bonding in NO2Cl which are shown in the image attached.
