The correct answer is 'arms length'. This is a tactical purchase (as it is low value) and keeping the supplier at arms-length means that Red Manufacturing could possibly exploit them to reduce their prices (think back to the Kraljic matrix and where Blue Business would likely fall). A Partnership or Single- Source relationship requires investment into the relationship, and as the products are low value and Red Manufacturing have a lot of other suppliers, they should not be investing time in developing that relationship with Blue Business. An adversarial relationship wouldn't be advantageous as it may lower the performance of the supplier. See the relationship spectrum on p.5 - this is a hot topic for the exam

The correct answers are; They are likely to be able to gain price stability and There may be greater continuity of supply. The other options are an advantage for the supplier rather than the buyer (They will gain an increased volume of business) and a disadvantage of entering into a partnership (The supplier may become complacent). As you may have guessed from these questions - Partnerships come up a LOT in the exam. See p.130 for info on pros and cons of partnerships.

The correct answer is 'Conduct regular audits'. This is explained on p.153. You wouldn't do an appraisal on a supplier in a partnership relationship as both parties are equal. Threatening a partner isn't good for the relationship and a damages clause would be used in a contractual relationship rather than a partnership.
