The correct answer is C. Building bridges and roads.
Explanation
When we talk about public works, we refer exclusively to the infrastructure works that are in charge of a government to benefit society. Within the public infrastructure are roads, highways, avenues, ports, airports, dams, hospitals, schools, street lighting, bridges, among others. These works can be built by direct contracting or public bidding, these two differ in that the first is through direct government contracting with a company, while the public bidding is an open call to construction companies to present their proposals and that the government chooses the one best suits their interests. So, the correct answer is C. Building bridges and roads.
