NOTE : Feel free to ask further queries. Your positive rating would be appreciated and motivate me !

In order to find the solution we only need to locate the given co-ordinates in the given phase diagram. The Si - 60% at V at 1900 ^oC is shown with a red spot in the figure below. The possible phase found in this region would just be the phase in the boundaries surrounding the red spot, and they are,

• L
• V₆Si₅
• V₅Si₃
