A student performs an experiment an for determination of `g(=(4pi^(2)l)/(T^(2)))`. The error in length `l` is `Deltal` and in time `T` is `DeltaT and n` is number of times the reading is taken. The measurment of `g` is most accurate for

Options

A. `{:(Delta l,Delta T,n),(5 mm,0.2" sec",10):}`
B. `{:(Delta l,Delta T,n),(5 mm,0.2" sec",20):}`
C. `{:(Delta l,Delta T,n),(5 mm,0.1" sec",10):}`
D. `{:(Delta l,Delta T,n),(1 mm,0.1" sec",50):}`
