$\dfrac {3}{2}$
0%
$2\dfrac {1}{3}$
0%
$2\dfrac {1}{2}$
0%
$3\dfrac {1}{2}$

Explanation

In the given image, clearly there are 2 full shaded parts and one half shaded part.
Therefore, figure represent

$2+\displaystyle \frac12$

$\Rightarrow 2\displaystyle \frac12$

Hence, option C is correct.

The above figure represents which of the following fractions?

0%
$\dfrac {9}{7}$
