Selected Answer: A

The main reason quantum computing advancements are driving companies and countries to deploy new encryption algorithms is: A. Encryption systems based on large prime numbers will be vulnerable to exploitation. Quantum computers, through algorithms like Shor's algorithm, have the potential to break current encryption systems, such as RSA, which rely on the difficulty of factoring large prime numbers. Quantum computing could make it feasible to quickly solve these problems, thereby rendering traditional encryption algorithms vulnerable. This has led to the development of post-quantum cryptography (PQC) algorithms that are resistant to quantum attacks. The other options are not as directly tied to the specific concern of quantum computing's impact on encryption:
