I need help on this i’m literally struggling :(

your answer is option d nuclear reaction bcz our body don't need these things

D.

Explanation:

I don't believe that living things have nuclear reactions.

They have 1 or more cells, they reproduce, and they have complex chemical activity, but I have never heard of living things having nuclear reactions so to this this is the one that makes sense

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this

the answer u all are looking for is 4000000000000000000000 million years.
