Process of elimination
eliminate choice B, since it has two odd numbers
--
multiples of 5, end in 5 or 0, but since one number has to be odd while another a multiple of 5, that means only those ending in 0 qualify, therefore, eliminate choice C
also eliminate choice D, since there would be two multiples of 5
--
that leave choice A and E, but since the third critiria states that it has to be a day of the month, eliminate choice E since 34 is too high for a day of the month

Answer: choice A
