Assertion (A): Batch correction saves considerably more money than initial recipe prediction.
Reason (R): It rescues material that would otherwise be reprocessed or scrapped.

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

Answer: B

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. A failed batch must otherwise be stripped, redyed or sold off, and the cost of that dwarfs the price of the dye in an initial recipe. Correction takes a batch already dyed and computes the small addition that brings it to standard, which is why the payback on a matching system usually comes from correction rather than prediction.
