Answer:
Long-term exposure to lead contaminants is most likely to result in:
c) Kidney problems.
Explanation:
Lead is a toxic metal that can accumulate in the body over time, particularly in bones and tissues. Chronic exposure to lead, such as through contaminated water from metal piping in a poorly built house, can lead to various health problems, including kidney damage. The kidneys are responsible for filtering waste and toxins from the blood, and lead toxicity can impair their function, leading to kidney problems over time. While lead exposure can also have other health effects, such as neurological damage, developmental issues in children, and cardiovascular problems, kidney damage is a significant concern due to the body's difficulty in eliminating lead once it enters the system.
