Angular - Fundamentals

Ang serve -p 4500 -o

Bng serve -p 4500 -o --live-reload=false

Cng serve --port=4500 --open --live-reload=false

Dng serve --port 4500 --open --live-reload=false

Step-by-Step Solution

Solution:

Step 1: Understand default live reload behavior
ng serve enables live reload by default, so no extra flag is needed.
Step 2: Choose correct syntax for port and open
Short flags -p 4500 and -o correctly set port and open browser.
Step 3: Eliminate options that disable live reload
Options B, C, and D include --live-reload=false which disables automatic reloading on code changes. Only A relies on the default behavior to ensure live reloads.
Final Answer:
ng serve -p 4500 -o -> Option A
Quick Check:
Live reload default + short flags = ng serve -p 4500 -o [OK]

Quick Trick: Live reload is on by default; just set port and open flags [OK]

Common Mistakes:

Adding --live-reload=false which disables live reload
Using incorrect flag syntax
Assuming live reload needs explicit enabling
