Given this Flask code, what will be printed when accessing /?

from flask import Flask
app = Flask(__name__)

@app.before_request
def before():
    print('Before request')

@app.route('/')
def home():
    print('Home route')
    return 'Hello'

ABefore request\nHome route

BHome route\nBefore request

COnly Home route

Final Answer:
Before request\nHome route -> Option A
