Why this answer is correct
Solution
Given Statements:
All nails are pins.
All pins are buttons.
The least possible Venn diagram for the given statement is:
Conclusions:
I. Some buttons are pins - Follows (Since all pins are buttons, the part of buttons occupied by pins shows that some buttons are definitely pins.)
II. All nails are buttons - Follows (Since all nails are inside pins and all pins are inside buttons, nails are also within the buttons circle.)
So, both conclusion I and II follow.
Hence, the correct answer is "Option 1".
