Answer 1

Answer ⇒ Option (a). Every measurement by any measuring instrument has some error.

Explanation ⇒

While doing measurements, errors depends upon the Skill and the Accuracy of the Observers and also on the Precision of the measuring instruments.

The measurements done from the different instruments can have the different errors. If they are done by the same instruments for the same object then also it can have the errors in the Random case, or in systematic case or the least count errors.

Thus, option (A). is the Incorrect statements.

Hence, Option (A). is the answer of the given Question.
