Which if the following is a benefit associated with nuclear energy

B sounds like the only one that is actually a benefit.
radiotion waste is not good so it cant be A
i have never heard of radiation used as fertilizer so it can be D
and i dont think its C.
i hope this helps

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
