Arsenic exposure increases the likelihood of which of the following?

Arsenic exposure is associated with an increased risk of developing cancer, making it the correct choice. This toxic element is categorized as a human carcinogen, with several studies demonstrating a direct link between arsenic exposure and various types of cancer, particularly skin, bladder, and lung cancers. Chronic exposure to arsenic can lead to cellular changes and DNA damage, contributing to the carcinogenic process.

The other options do not correlate with the effects of arsenic exposure. Healthy bone development typically requires adequate nutrition and does not have a direct connection with arsenic. Developing respiratory infections generally results from pathogens or environmental factors rather than arsenic exposure specifically. Receiving vaccinations is a separate public health issue focused on disease prevention and is not influenced by arsenic levels in the body. Thus, the connection of arsenic exposure to the development of cancer clearly establishes it as the correct answer.
