Which of the following is a result of exposure to an oncovirus?

Development of immunity
Formation of tumors
Immediate cell repair
Enhanced metabolism

The correct answer is: Formation of tumors

Exposure to an oncovirus is primarily associated with the formation of tumors. Oncoviruses are a type of virus that can lead to cancer by altering the genetic material of host cells. When oncoviruses infect cells, they may integrate their own genetic material into the host's DNA or produce proteins that disrupt normal cellular functions. This disruption can lead to uncontrolled cell division, thereby facilitating tumor formation. While immunity can develop in response to viral infections, this is not a direct result linked to oncoviruses; rather, it's a general immune response. Immediate cell repair is a normal cellular mechanism to respond to damage but does not specifically relate to the effect of oncoviruses. Lastly, enhanced metabolism is not a direct outcome of oncoviral infection; while cancer cells can exhibit altered metabolic processes, this is more of a consequence of tumor development rather than a direct result of oncoviral exposure.
