The question asks for the number of stereoisomers possible for the given molecule, but the actual structure/image of the molecule is missing from the prompt.

Without the molecular structure, it is not possible to determine the number of stereoisomers, because that depends on factors such as:

1. Number of stereocentres
2. Presence of symmetry (meso form may reduce the count)
3. Geometrical isomerism ($E/Z$, cis/trans)
4. Axial or conformational chirality, if any

In general:

• If a molecule has $n$ chiral centres and no symmetry, maximum stereoisomers $=2^n$.
• If symmetry is present, the actual number may be less due to meso forms.

Since the molecule itself is not provided, I cannot verify whether the answer should be $2$, $1$, $3$, or $4$.

Therefore, I cannot reliably agree with the stored answer solely from the given text.
