none of the above; the triangles cannot be proven similar

Explanation:

Step1: Check the ratio of corresponding sides

For triangle \(RQS\) and \(VTS\), \(\frac{RQ}{VT}=\frac{32}{48}=\frac{2}{3}\), \(\frac{RS}{VS}\) (assuming \(VS = 72\) and \(RS = 48\)) is not relevant as we need to check the sides around the included angle. Wait, actually, for \(\triangle RQS\) and \(\triangle VTS\), \(\angle R=\angle T = 96^{\circ}\). The sides around \(\angle R\) in \(\triangle RQS\) are \(RQ = 32\) and \(RS\) (let's assume the other side adjacent to \(\angle R\) is \(RS\)), and the sides around \(\angle T\) in \(\triangle VTS\) are \(VT=48\) and \(TS\) (assuming the other side adjacent to \(\angle T\) is \(TS\)). Wait, no, actually, if we consider the ratio of sides \(\frac{RQ}{VT}=\frac{32}{48}=\frac{2}{3}\), \(\frac{QS}{TS}\) (assuming \(QS\) and \(TS\) are the other sides). Wait, no, using the SAS (Side - Angle - Side) similarity criterion: If two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar. Here \(\frac{RQ}{VT}=\frac{32}{48}=\frac{2}{3}\), assume \(QS\) and \(TS\) (if \(QS\) corresponds to \(TS\)) \(\frac{QS}{TS}\) (if \(QS\) is \(x\) and \(TS\) is \(\frac{3}{2}x\)) and \(\angle R=\angle T = 96^{\circ}\).

Step2: Apply the SAS similarity criterion

The SAS (Side - Angle - Side) similarity theorem states that if \(\frac{a}{a'}=\frac{b}{b'}\) and the included angles \(\theta=\theta'\), then the two triangles are similar. In \(\triangle RQS\) and \(\triangle VTS\), \(\frac{RQ}{VT}=\frac{32}{48}=\frac{2}{3}\), and \(\angle R=\angle T = 96^{\circ}\).
