Assertion (A): A colourist remains necessary despite the software.
Reason (R): Fastness, compatibility and process knowledge are outside what the calculation covers.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason gives the mechanism. The software solves one well-defined problem - what concentrations give this colour - and is silent on whether the dyes are fast enough, whether they exhaust compatibly in one bath, and whether the shade can be held in bulk production. Those judgements remain with the colourist, and the system is a tool rather than a replacement.
