Answer:
d) derived
Explanation:
Derived demand is when a supplier is interested in a product not for itself, but for other associated products.
Paula is interested in New homes that are being constructed not because of the homes themselves, but she wants to sell electronics the new home owners.
It is similar to joint demand and complimentary demand as increase in one product leads to increase in the other.
The more houses being built the more electronics Paula will sell.
