What does the term "innate" refer to in a person?

The term "innate" refers to qualities or characteristics that a person possesses from birth, implying that these traits are inherently part of their nature rather than learned or influenced by external factors. This concept is often used in discussions about natural talent, instincts, or inherent abilities that do not require external teaching or experience to develop. In contrast, the other options describe qualities or traits that result from various influences, experiences, or events in a person's life, which are not consistent with the definition of "innate." Therefore, the selection that states "existing in a person since birth" aligns perfectly with the meaning of "innate."
