Answer:
The correct answer is option a. new goods bias.
Explanation:
The new goods bias arises from not taking into account new products within a price index. As these products are new, and are not used on a regular basis, they are not included in the CPI (which is the consumer price index, where the prices of products that are consumed regularly by a family are valued).
Due to technology, prices may decrease, therefore this would generate a problem when accurately measuring changes in the cost of living.
