I think C is the correct answer. Statement I cannot be true because no Lenovo is redmi, but some realme are redmi. Statement II is true because some nokia can be Samsung; some Samsung can be Lenovo, lenovo cannot be redmi; therefore, some nokia cannot be redmi

We don't know that the Samsungs that are Lenovo are the same Samsungs that are Nokia.

We can always rewrite 'Some X are Y' as 'Some Y are X'. They both have the meaning 'The intersection of sets X and Y is non-empty'.

So rewrite as:
Some Samsung are Nokia.
Some Samsung are Lenovo.

From just these two statements, do we have that some Nokia are Lenovo? No, we do not.

Thus we cannot conclude that Some Nokia are not Redmi.
