Which of the following is not an example of a modifiable behavior? A. Genetics B. Sexual Activity C. Diet D. Cigarette Smoking

Step 1: Break Down the Problem

The question asks to identify which option is not a modifiable behavior from the given choices. Modifiable behaviors are those that an individual can change or control, while non-modifiable behaviors are often determined by genetics or other factors outside an individual's control.

Step 2: Relevant Concepts

1. Genetics: Refers to the biological inheritance of traits, which cannot be changed by individual effort.
2. Sexual Activity: This can be modified based on personal choices and circumstances.
3. Diet: An individual's dietary choices can be changed and are considered a modifiable behavior.
4. Cigarette Smoking: This is a behavior that can be altered, as individuals can choose to quit smoking.

Step 3: Analysis and Detail

By analyzing each option:

• A. Genetics: This is innate and cannot be changed by the individual, thus it is not modifiable.
• B. Sexual Activity: This is influenced by personal decisions and preferences.
• C. Diet: A person's diet can be modified through choices.
• D. Cigarette Smoking: This behavior is modifiable as one can decide to start or quit smoking.

Step 4: Verify and Summarize

After considering all options, it is clear that genetics is the only option that does not fall under modifiable behaviors, as it is inherent and fixed.

Final Answer

A. Genetics is not an example of a modifiable behavior.
