Answer:
(c) $535,528.03
Explanation:
You want to know the balance required to support semiannual withdrawals in the amount of $15,265 for 35 years from an account earning 4.5% interest compounded semiannually.
Present value
The value of this ordinary annuity can be calculated from ...
PV = A(n/r)(1 -(1 +r/n)^(-nt))
where amount A is withdrawn n times per year for t years, with interest rate r. Payments are assumed to be at the end of each half-yearl period.
PV = 15265(2/0.045)(1 -(1 +0.045/2)^(-2·35)) ≈ 535,528.03
The amount needed is about $535,528.03.

Additional comment
If withdrawals are made at the beginning of each period, the amount required is 2.25% more: $547,577.41.
