Concept:In syllogism, a possibility conclusion follows unless it directly contradicts the given statements.
Explanation:"Only a few planet are metal" means some planet are metal and some planet are not metal.
"Some metal are storm" and "No storm is silent" are given facts.
Conclusion I: Some planet being storm is a possibility.
There is no direct relation between planet and storm, so their overlap is not ruled out.
Thus, possibility I logically follows.
Conclusion II: No metal is silent.
Only those metal which are storm are definitely not silent, because no storm is silent.
The remaining metal may or may not be silent.
Therefore, the definite conclusion "No metal is silent" does not follow.
Answer:Only conclusion I follows.
Hence, the correct option is A.
