Final answer:
A checking account is a type of depository account that individuals use to pay bills and make purchases. Omar and Lian opening a savings account does not imply that they also opened a checking account.
Step-by-step explanation:
A checking account is a type of depository account that individuals use to pay bills and make purchases. It is different from a savings account because it allows for frequent withdrawals and transactions. Omar and Lian opening a savings account does not imply that they also opened a checking account, so the statement 'Omar and Lian each open a checking account' is false.
