The correct Answer is:
To solve the question, we need to identify the terms that correspond to A, B, and C in the statement provided. ### Step-by-Step Solution: 1. **Identify A**: - The question states that normal cells have genes that are present in an inactivated state. These genes are known as **proto-oncogenes**. - **A = proto-oncogenes** 2. **Identify B**: - The question mentions that under certain conditions, these genes can be transformed. One of the primary conditions that can lead to the activation of proto-oncogenes is **mutations**. - **B = mutations** 3. **Identify C**: - When proto-oncogenes are activated due to mutations, they can become **oncogenes**, which are genes that can promote cancer development. - **C = oncogenes** ### Final Answer: - A = proto-oncogenes - B = mutations - C = oncogenes
