Question is vague, where does it say that the bond in question is a treasury? It just says that it’s a bond, and that 3 months down the line, treasury yields decrease.
You would have to know the actual treasury yield versus the bond coupon to determine if it’s a discount or premium, so assuming that they are referring to 4.2% (5.2%  100 bps drop) as the treasury rate, yes, coupon>yield = premium in 3 months.
