Problem

An individual who has a pathogen but shows no effects is a 

A. mutant

B. carrier

C. vector

D. incident

Solution

A disease may be acquired through different means. This may be through a genetic mutation or through transmission - by a vector or by a carrier. A specific portion of the individual's genetic information may be altered naturally during cell division or when the individual is exposed to mutation-inducing agents. This genetic alteration might lead to a nonfunctional protein which causes the disease.
