Light from three different lasers (A, B, and C), each with a different wavelength, was shined onto the same metal surface.

Laser A produced no photoelectrons. Lasers B and C both produced photoelectrons, but the photoelectrons produced by laser B had a greater velocity than those produced by laser C.

Arrange the lasers in order of increasing wavelength.

a) A < B < C 

b) B < C < A

c) C < B < A 

d) A < C < B
