Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statements:
I. Some zinc is iron.
II. Some zinc is silver.
III. No silver is gold.
Conclusions:
l) Some zinc is not gold.
II) Some zinc is gold.
III) Some silver is iron.

​Statements:
I. Some zinc is iron.
II. Some zinc is silver.
III. No silver is gold.

​Conclusions:

l) Some zinc is not gold. (Not follows, Since no silver is gold, and zinc overlaps with silver (statement 2), those parts of zinc that are silver cannot be gold.)
II) Some zinc is gold. (Not follows, There is no statement supporting any overlap between zinc and gold.)

III) Some silver is iron. (Not follows, There is no information showing silver and iron overlap directly.)

Thus, correct option is (b).
