What is wrong with this Flask-Caching setup code?

from flask import Flask
from flask_caching import Cache

app = Flask(__name__)
cache = Cache()

@cache.cached(timeout=30)
@app.route('/')
def home():
    return 'Welcome!'

cache.init_app(app)

AThe order of decorators is incorrect; @app.route should be above @cache.cached

BCache must be initialized before defining cached routes

Ccache.init_app(app) should be called before using @cache.cached

DNo error; this code works correctly

Step-by-Step Solution

Solution:

Step 1: Check decorator order
In Flask, @app.route must be the outer decorator, so it should be above @cache.cached.
Step 2: Understand decorator stacking
Incorrect order causes the route not to register properly, breaking caching behavior.
Final Answer:
The order of decorators is incorrect; @app.route should be above @cache.cached -> Option A
Quick Check:
Decorator order matters = B [OK]

Quick Trick: Place @app.route above @cache.cached [OK]

Common Mistakes:

MISTAKES

Swapping decorator order
Thinking cache.init_app must be before decorators
Assuming no error with wrong decorator order
