<reasoning>

Analyze communication methods in high-noise environments

In industrial pressure washing and jet blasting operations, high-noise levels make verbal communication like yelling ineffective and unsafe.

Evaluate the safety and reliability of each option

• Line of sight with hand signals (A): Highly effective and standard when operators can see each other.
• Two way radio (B): Standard and reliable for non-line-of-sight or distant communication.
• Yelling really loud (C): Unreliable and unsafe due to equipment noise and hearing protection.

Determine the correct combination

Since both A and B are recognized safe methods of communication, the correct choice is D (A and b).
