And igneous rock sample is about 250,000 years old. would you use uranium-lead radiometric dating to find its age?

Yes, wikipedia says "It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range."

Therefore, 250,000 years can be compared

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.

Ashould be answer.
