Salvatore and Harriet recently got married. They are presently renting but are looking forward to buying a new home within $5$ years. They both have separate savings established in their respective registered retirement savings plans $($RRSPs$)$ of $$100,000$ each. They have come to Dustin, a Dealing Representative, to open an additional joint investment account to increase their savings to assist with their future plans of buying a new home.

What does Dustin need to ensure about his recommendation?

That the recommended investment is different from what they currently own to avoid over$-$concentration.

That the risk profile for this new account is the same as what has been determined for other accounts.

That the risk profile of the investment and each client's individual risk profile are a match.

That the investment recommendation is based on the risk profile of the new joint account.
