A student performs an experiment for determination of ` g [ = ( 4 pi^(2) L)/(T^(2)) ] , L ~~ 1m` , and he commits an error of `Delta L`. For `T` he takes the time of `n` oscillations with the stop watch of least count ` Delta T` . For which of the following data , the measurement of `g` will be most accurate ?

Options

A. `{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.2sec,,10,,5mm):}`
B. `{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.2sec,,20,,5mm):}`
C. `{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,5mm,,0.1sec,,20,,1mm):}`
D. `{:(,Deltal,,DeltaT,,n,,"Amplitude of oscillation"),(,1mm,,0.1sec,,50,,1mm):}`
