Answer:
There are chiral centers on the molecule thus making it a molecule with stereoisomers.
Step-by-step explanation:
Stereoisomerism is defined: a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
The easiest way to see if this definition is true for any molecule is to see if there are any chiral centers / asymmetric centers. To do this, you would need to look for an sp3 hybridized (tetrahedral) carbon on the molecule with four different groups attached to it. For example, the C in -CH3 would not be a chiral center as there are 3 of the same H's attached to it.
On the given molecule there are 4 chiral centers which makes it a chiral molecule and thus a stereoisomer. Any molecule with one or more chiral centers has stereoisomerism. In this molecule it is easy to see as the chiral centers are the carbons with the wedges and dashes bonded to them indicating the 3D orientation of the constituents. With dashes denoting into page toward the back, and wedges denoting out of the page toward you.
