Daily rate = 0.1204/365 = 0.0003301369863. The payment reduces the balance to 606.40 − 55.25 = 551.15.
If the payment is made on day d, the sum of daily balances is (d−1)(606.40) + (31−d)(551.15) = 55.25d + 16,479.25. The finance charge is this sum times the daily rate:

0.0003301369863(55.25d + 16,479.25) = 5.71.

Solving gives d ≈ 15.04, so the payment was made on June 15th.

Answer: c. June 15th.
