given the following class definition, how could you use the constructor to assign values to an object of this class?

class CDAccount
{
public:
CDAccount();
CDAccount(float interest, float newBalance);
float getBalance();
float getRate();
void setRate(float interest);
void setBalance(float newBalance);
private:
float balance, rate;
};

and the following object declaration
CDAccount myAccount;
a. myAccount = CDAccount(float myRate, float myBalance);
b. myAccount = CDAccount {myRate, myBalance};
c. myAccount = CDAccount[myRate, myBalance];
d. myAccount = CDAccount(myRate, myBalance);

d. myAccount = CDAccount(myRate, myBalance);
