Answer:
B) less than zero.
Step-by-step explanation:
Since the coffee and the coffee cream are consumed and used together so they are considered to be the complement goods to each other
In this case, the cross price elasticity of demand is negative and while on the other hand if the two goods are considered to be a substitute than this would be a positive
Hence, it should be less than zero i.e. negative
Therefore the correct option is B.
