Answer
$1.0\%$
$1.004 \%$
$1.005\%$
Work Step by Step
(a) The effective annual rate for an account paying $1 \%$ compounded annually is $1 \%$
(b) The interest rate per quarter is $0.01 / 4$. Therefore, the effective interest rate is
$$i= \left(1+\frac{0.01}{4}\right)^{4}-1= 1.004 \%$$
(c) The interest rate per day is $0.01/ 365$. Therefore, the effective interest rate is
$$i= \left(1+\frac{0.01}{365}\right)^{365}-1= 1.005 \%$$
