To answer this, I must assume that the question specifically ask on what type of product a cement is since no choices are given.
Cement cannot be a service product since obviously it is a tangible product. Service products are those which typically the quality of service is more significant than the physical product such as cleaning, massage and etc.
Cement cannot also be a consumer product since it is not being used by a specific person or consumer in this case.
Therefore cement is a “Industrial product” since it is used by a specific business or industry for further processing such as creation of buildings and etc.
Answer: Industrial product
