Exploring the Origin of Elements to Nucleosynthesis and Fusion in Stars

[Orion78]

By choosing among the following five options, what is the main source in the universe for the origin of the elements : silicon, lithium, bismuth, nickel and uranium?

Primordial nucleosynthesis – fusion in core of low-mass stars – fusion in core of high-mass stars – slow neutron capture in high mass-stars - rapid neutron capture in supernovae.

Thanks

Sorry, next time I will choose the right forum.
The following is what I think is the right answer but I'd like to be confirmed.

silicon = Fusion in core of low-mass star
lithium = Primordial nucleosynthesis
bismuth = Low neutron capture in high mass-stars
nickel = Fusion in core of low-mass star
uranium = Rapid neutron capture in supernovae

Thanks!

For nickel I think you mean fusion in the core of a HIGH mass star. Also, isn't silicon one of the last elements produced in high mass stars and not low mass stars? I'm not formally educated in astrophysics so I could be wrong.

for your interest in the origins of elements! The main source for the origin of the elements listed would depend on the specific element in question. For example, silicon is primarily formed through fusion in the cores of low-mass stars, while lithium is primarily formed through primordial nucleosynthesis. Bismuth, nickel, and uranium are primarily formed through slow neutron capture in high-mass stars, with some contribution from rapid neutron capture in supernovae.
