Which of the following is the correct way to define a simple health check endpoint in Flask?

Aapp.route('/health') def health(): return {'status': 'ok'}

B@app.route('/health') health = {'status': 'ok'}

Capp.route('/health') health = lambda: {'status': 'ok'}

D@app.route('/health') def health(): return {'status': 'ok'}

Step-by-Step Solution

Solution:

Step 1: Recall Flask route decorator syntax
Flask uses @app.route('/path') decorator above a function to define routes.
Step 2: Check each option for correct syntax
@app.route('/health') def health(): return {'status': 'ok'} correctly uses @app.route decorator and defines a function returning a dictionary. Others miss the decorator or define incorrectly.
Final Answer:
@app.route('/health')\ndef health():\n return {'status': 'ok'} -> Option D
Quick Check:
Use @app.route decorator for routes [OK]

Quick Trick: Use @ before app.route to define Flask routes [OK]
