Why does this Flask CLI command raise an error?

from flask import Flask
app = Flask(__name__)

@app.cli.command()
@click.option('--count', default=1)
def repeat(count):
    for _ in range(count):
        print('Repeat')

Command run: flask repeat --count five

BThe command name 'repeat' is invalid

CMissing @click.argument decorator

DFlask app instance is not initialized

Final Answer:
The option 'count' expects an integer but received a string -> Option A
Quick Check:
