Angular - Templates and Data Binding

Identify the error in this Angular template snippet:

{{ user?.address.city }}

where user can be null or have address as null.

ANo error, safe navigation is used correctly

BError because safe navigation operator cannot be chained

CError because <code>city</code> is accessed without safe navigation

DError because <code>user</code> is not checked for null

Step-by-Step Solution

Solution:

Step 1: Analyze safe navigation usage
The snippet uses user?.address.city. The safe navigation is only before address, not before city.
Step 2: Identify potential null access
If user is not null but address is null, accessing city without safe navigation causes an error.
Final Answer:
Error because city is accessed without safe navigation -> Option C
Quick Check:
Chain safe navigation for nested nulls [OK]

Quick Trick: Use ?. before each nested property to avoid errors [OK]
