That's right.

Which of these two placards must be displayed regardless of quantity, if they are a subsidiary hazard?

Scenario: The truck has no placards and contains no other materials. The shipper is offering 1,005 lbs. of a Division 5.1 Oxidizer in non-bulk packages. Must the shipper offer placards?
Not quite.
Shippers must offer placards for vehicles carrying non-bulk packages that contain an aggregate gross weight of 1,001 lbs. or more of the hazardous materials identified in Table 2 to 49 CFR 172.504(e). If only one Table 2 material is present in the vehicle, then the specific placard for that material must be used.
In this scenario, because Division 5.1 is identified in Table 2, and it is the only Table 2 material offered, the shipper must provide Division 5.1 placards.
