Verified Answer :

I think it's 27 units

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,

\(C=\pi d\\\\\Rightarrow 85=\dfrac{22}{7}\times d\\\\\Rightarrow d=\dfrac{85\times 7}{22}\\\\\Rightarrow d=27.04545...\)

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

Option (B) is CORRECT.
