Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : If the device is left out on the worktable "faint ghost band" appears at the test region.
Reason (R) : The unbound conjugate deposited on the test band results in appearance of a faint ghost band.
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Never interpret a lateral flow assay outside the manufacturer's recommended time window! Evaporation lines (ghost bands) are the most common cause of false-positive interpretations in at-home testing.
