Answer 2

Answer:

OPTION (b) Student B

Explanation:

• Precision and accuracy are two different ways used by scientists while analyzing errors.
• The closer a measurement is to the accepted value, the more accurate it is.
• On the other hand, precision is when two measurements of the same item are close to each other.

In the given question, Student B has the most accurate and precise value, which is $4.001$ seconds.

Hence, option (b) Student B ($4.001 \ sec$) is the right answer.
