What is an experiment?

An experiment is a set of observations, performed while solving a particular problem or question.

Science is always changing, so experiments need to be repeated.

The accuracy of a measurement is dependent on the quality of the  apparatus and the skill of the scientist engaged. For data to be considered reliable, any variation in values should be small. Repeating a scientific investigation makes it more reliable.

Repeating an experiment, under the same conditions, allows for estimating the accuracy.

Hence, option D is correct.
