Final answer:
In accordance with IFRS 15, contracts must be combined and accounted for as a single contract in certain scenarios. Option A and Option B both meet the criteria for combining contracts.
Step-by-step explanation:
In accordance with IFRS 15, entities are required to combine contracts and account for them as a single contract in certain scenarios. In the given scenario, Option A meets this criterion as Interior Supply World Ltd. entered into contracts with three unrelated interior design companies to supply furniture and décor accessories for home interiors.
Another scenario that would require the combination of contracts is when the contracts have different characteristics, commercial objectives, and independent consideration. Option B meets this criterion as Project Ltd. entered into three separate contracts with Learning Inc.
Each with different characteristics and commercial objectives, and independent consideration for each contract. Therefore, the correct options that would require combining the contracts and account for them as a single contract in accordance with IFRS 15 are Option A and Option B.
