Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understand the task:
Find the set in which two statements give the third.
Step 2: Test option (B) BEF:
B: Everyone sane can do logic. E: Everyone who can do logic is fit to serve on a jury. So everyone sane is fit to serve on a jury, which is F. So B and E together imply F.
Step 3: Check the others:
(A) BDE: D is a particular statement and E is a universal statement; D already follows from E (given that some can do logic), so there is no deduction using B.
(C) BDF: B and D (particular) give nothing about F.
(D) ADE: A is about lunatics and the others are not connected to it.
Final Answer:
The correct option is (1): BEF (B and E together give F).
