Answer:
The most important requirement for an emergency fund is LIQUIDITY, because Laura will need QUICK ACCESS TO HER SAVINGS.
Explanation:
An emergency by definition is something unexpected or unplanned, therefore if Laura wants to have some money set apart to cover any expenses originated by an emergency, the best option is to keep the money in a savings account. A savings account is very liquid, and in case you need some money you can transfer it (online transfer) to your checking account.
