In which situation can quality variation increase during collective production in an Indian food business?

Correct answer: When different members change measurements and spices by guess

The direct answer is option C. In collective production, quality variation increases when different members measure ingredients or change spices by guesswork. First, one person may use more salt; another may use less water; a third may cook for a different time. These small differences change taste, texture, colour, quantity and sometimes safety. Option C is correct because it removes standardisation. Option A is wrong because following one recipe makes results more uniform. Option B is wrong because regular ingredient checking reduces mistakes and variation. Option D is wrong as a reason for increasing variation: final inspection can detect defects, although it cannot always repair a poorly standardised process. The best system uses a written recipe, fixed measurements, defined cooking time and trained staff. Memory cue: same recipe, same measure, same result.
