I tackled it this way (don't know the official explanation)
"The product of a positive multiple of 5 and an odd number" will always end in 0 or 5, otherwise it would not be a multiple of 5.
Plus, these integers must be odd, so we know they must end in 5.
Positive odd integers less than 60 that end in 5: 5 - 15 - 25 - 35 - 45 - 55
This asks for unique integers, so 6 is the answer.
Answer (E) IMO.
