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 conclusion(s) logically follow(s) from the statements.
Statements:
1. All trunks are peanuts.
2. Some grains are trunks.
3. No crows are trunks.
Conclusions:
I. Some grains are not crows.
II. Some peanuts are not grains.

​Statements:
1. All trunks are peanuts.
2. Some grains are trunks.
3. No crows are trunks.

​Conclusions:
I. Some grains are not crows. (True, so those grains that are trunks cannot be crows, because trunks and crows are disjoint).
II. Some peanuts are not grains. (False, it's possible that all peanuts are grains, or only some are. So we cannot conclude this definitely).

So, ​Only conclusion I follows.

Thus, correct option is (c).
