Answer:
option D
Explanation:
the correct answer is option D
A precise measurement is one in which we can measure the smallest of the value.
In 17.775 we can measure the smallest value of 0.001
In 18.55 we can measure smallest value up to 0.01
In 17.5 we can measure smallest value up to 0.1
In 18 we can measure smallest value of 1.
hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.
