Question: Pick the best description for this template syntax code:

1. The ? is shorthand for the async pipe. The job value must be an Observable.
2. It is using the safe navigation operator (?) on the job field. If the job field is undefined, the access to the bossName will be ignored and no error will occur.
3. There is an error in the template syntax. The ? is not valid here.
4. It is diplaying the job value if it has one; otherwise it is displaying the bossName.

Answer: The correct answer of the above question is Option B:It is using the safe navigation operator (?) on the job field. If the job field is undefined, the access to the bossName will be ignored and no error will occur.
