Suppose you are building an application which requires sending emails to all the users stored in the database at regular intervals. Given below are the two approaches to satisfy the requirement. Approach 1: @celery.task def send_bulk_emails(): all_users = User.query.all() // Get all the user objects from the database for user in all_users: // send email to the user send_bulk_emails.delay() // invokes celery task Approach 2: @celery.task def send_email(email): // send email to the user all_users = User.query.all() // Get all the user objects from the database for user in all_users: send_email.delay(user.email) // invokes celery task Choose the correct statement(s).

(A) Approach 1 will take more time than approach 2, if more than 2 celery workers are available.

(C) Both the approaches will take same time (approx), if only 1 celery worker is available.

(B) Approach 2 will take more time than approach 1, if more than 2 celery workers are available.

Suppose you are building an application which requires sending emails to all the users stored in the database at regular intervals. Given below are the two approaches to satisfy the requirement.

Approach 1:

python

1@celery.task
2def send_bulk_emails():
3    all_users = User.query.all() // Get all the user objects from the
4database
5    for user in all_users:
6        // send email to the user
7
8send_bulk_emails.delay() // invokes celery task

Approach 2:

python

1@celery.task
2def send_email(email):
3    // send email to the user
4
5all_users = User.query.all() // Get all the user objects from the database
6for user in all_users:
7        send_email.delay(user.email) // invokes celery task

Choose the correct statement(s).

Select all that apply.

A
Approach 1 will take more time than approach 2, if more than 2 celery workers are available.
B
Approach 2 will take more time than approach 1, if more than 2 celery workers are available.
C
Both the approaches will take same time (approx), if only 1 celery worker is available.
D
None of these
