Two clocks are being tested against a standard clock located in a national laboratory At 12 : 00 : 00 noon by standard clock, the readins of the two clocks are {:("Day","Clock - I","Clock - II"),("Monday",12:00:05,10:15:06),("Tuesday",12:01:15,10:14:59),("Wednesday",11:59:08,10:15:18),("Thursday",12:01:50,10:15:07),("Thursday",12:01:50,10:15:07),("Friday",11:59:15,10:14:53),("Saturday",12:01:30,10:15:24),("Sunday",12:01:19,10:15:11):} From the Observations carefully read the following conclusive statements. Statement I : Zero - error in clock II is much longer than zero - error in clock I. Statement II : Zero - error can always be corrected by applying necessary corrective measures Statement III : Precision of clock - I is more than precision of clock - II Statement IV : Precision of clock - II is more than precision of clock - I Pick up the correction option from the following.
