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.
