Answer:
The correct answer is letter "B": injurious to public service.
Step-by-step explanation:
Contracts that are injurious to public service are those where public deputies deviate from their duties going out of the law. In most cases, the deviation implies using public resources incorrectly to benefit a third party or the representative in charge of allocating those resources efficiently. The contract is injurious to public service because it decreases the benefits the population should receive according to what central authorities have provided.
