Expert Answer
Most likely recorded value of mass : - (C) 64.3 kg
Mass values given in (B) and (C) i.e., 60 kg and 64.3 kg are reasonable
but other values are unlikely mass value for an adult person
Mass value given in (B) i.e., 60 kg is without any fraction. When mass is measured accurately with less than 0.5% error,
getting a value without fraction is unlikely
if we consider (C) i.e., 64.3 kg, we assume the true mass is nearly 64 kg, then this excess 0.3 kg is less than 0.5% .
Hence (C) 64.3 kg is most likely value of mass
