Which describes how transuranium elements are made in a lab? by the transmutation of protons to electrons in a stable element by the artificial transmutation of a lighter element by the artificial transmutation of carbon compounds

The correct answer is by the artificial transmutation of a lighter element.

Explanation:

The transuranic elements are also called transuranium elements. Uranium has atomic number 92. Transuranium are the chemical elements that exhibit atomic numbers of more than 92, they are not stable, are radioactive, and are generally not found in nature.  

Transmutation is the transformation of the atoms of one element to the atoms of another. No chemical modification takes place in the process, however, it does incorporate a nuclear change. The process of artificial transmutations takes place when the atomic nuclei are encountered with high energy particles like neutrons, protons, or alpha particles.  

the answer is either b or c
