01 A pharma company checks quality before batch release but does not verify validity of the testing equipment. Which control is weak?
Answer and explanation
Correct answer: C. Equipment validity and result reliability control
Explanation: The direct answer is C: equipment validity and result reliability control. A quality check can protect a batch only if the instrument gives accurate and dependable measurements. The reasoning is: the company tests the product; the test result depends on the equipment; if the equipment has not been verified as valid, a good result may be false and a bad result may also be missed; therefore the control over equipment validity and reliability is weak. Option A is wrong because greeting customers has no direct connection with laboratory measurement. Option B is wrong because sales promotion concerns marketing, not test accuracy. Option C is correct because it names calibration or validity and the trustworthiness of results. Option D is wrong because dividends concern distribution of profit, not pharmaceutical quality. Exam cue: whenever a measurement is used, check the instrument, method and reliability before trusting the result.
