Explanation
Diversification is the mutual fund benefit that would address Jasmine's concern about volatility.
Diversification means spreading investments across different asset classes, sectors, regions, and companies to reduce risk and volatility. A mutual fund provides diversification by pooling money from many investors and investing in a portfolio of securities that meet the fund's investment objective and strategy. By investing in a mutual fund, Jasmine can gain exposure to the energy sector without putting all her money in one company.
She can also benefit from the professional management and research of the fund manager, who can select and monitor the best securities for the fund. References: Mutual Funds, Diversification

Explanation
The federal tax on eligible Canadian dividends is calculated as follows:
First, the dividend amount is grossed up by 38%, which means multiplying it by 1.38. This is to account for the corporate tax that has already been paid by the company. Eleanora's grossed-up dividend is $500 x 1.38 = $690.
Second, the grossed-up dividend is multiplied by the federal marginal tax rate to get the gross federal tax. Eleanora's gross federal tax is $690 x 0.29 = $200.10.
Third, the grossed-up dividend is multiplied by the federal dividend tax credit rate to get the federal tax credit. This is to avoid double taxation of the dividend income. Eleanora's federal tax credit is $690 x
0.1502 = $103.64.
Fourth, the federal tax credit is subtracted from the gross federal tax to get the net federal tax. Eleanora's net federal tax is $200.10 - $103.64 = $96.46.
Therefore, Eleanora will pay $96.46 in federal tax on her dividend. References: How Dividends Are Taxed and Reported on Tax Returns - Investopedia, Dividend Tax Credit in Canada - TurboTax

Explanation
A mutual fund trust is a type of unit trust that meets certain conditions under the Canadian Income Tax Act and is eligible for favourable tax treatment. A unit trust is a collective investment vehicle that holds assets and distributes profits to individual unit owners, also called unitholders, instead of reinvesting them in the fund. A mutual fund trust is not a corporation and does not have a board of directors or shareholders. It is also not a closed-end fund, which has a fixed number of shares that trade on an exchange. A mutual fund trust is an open-end fund, which can issue and redeem units at any time based on the net asset value of the fund.
