Answer: The correct option is (B) 27 units.

Step-by-step explanation: Given that a circle has a circumference of 85 units.

We are to find the approximate length of diameter of the circle.

The circumference of a circle with diameter d units is given by

$C=\pi d.$

In the given circle, we have

C = 85 units, diameter, d = ?

So,

$C=\pi d\\\\\Rightarrow 85=(22)/(7)* d\\\\\Rightarrow d=(85* 7)/(22)\\\\\Rightarrow d=27.04545...$

Thus, the approximate length of the diameter is 27 units.

Option (B) is CORRECT.
