d$.$ If you are interested in decreasing the beta of your portfolio by changing your portfolio allocation in two stocks, which stock would you decrease and which would you increase? Why? $($Select the best choice below.$)$

A$.$ You should decrease asset $D$ and increase asset A because asset D$\text{'}$s beta is negative and asset A has the highest beta.

B$.$ You should increase asset A and decrease asset $D$ because asset D$\text{'}$s beta is negative and asset A has the highest beta.

C$.$ You should increase asset $D$ and decrease asset A because asset $D\text{'}$s beta is negative and asset A has the highest beta.

D$.$ You should increase asset $B$ and decrease asset $C$ because asset $B^{\text{'}}$ beta is close to $1$ and asset $C\text{'}$s beta is the closest to zero.
