Best answer
Correct answer is (a) Laser

Best explanation: Laser drilling provides consistency for manufacturing specifications relying on tight tolerance for high depth to diameter ratios. Laser drilling hole sizes vary depending on laser power, Motion Control and galvo system. Rapid prototyping is particularly adaptable to a wide range of hole sizes.
