Answer:
The account should be opened as a Joint account with tenancy in common. Option C.
Explanation: This type of account is one that is owned by at least two people and in which there is no rights of survivorship.
In this type of account, the members do not want their investments to go to other members of the joint account upon their death, but they specify in a will how the investment will be distributed to their beneficiaries.
Joint account with tenancy in common can hold an unequal amount of investment among members, but they still have equal rights to the account.
