The correct answer is:
The Lewis structure for methyl isocyanate, CH3NCO, including resonance forms, is:
```
H
|
C
/ \
H N=C=O
```
The skeletal structure is:
```
H
|
C
/ \
H N-C-O
```
The key points are:
1. The central carbon atom is connected to a methyl group (CH3), a nitrogen atom, and an oxygen atom.
2. The nitrogen atom is connected to the carbon and has a double bond to the oxygen atom.
3. The structure exhibits resonance, where the double bond can be delocalized between the nitrogen-carbon and carbon-oxygen bonds.
4. All atoms have a formal charge of 0 in the resonance structures.
